Research for this paper was undertaken into the relationship between public opinion on wind power and public participation in turbine site planning and design. The research focussed on the contribution of environmental attitude studies to participatory environmental impact assessment of renewable energy policy and land use. A questionnaire survey was undertaken at wind farm sites at three stages in the site planning process and at three public events where the application of wind power was a topic of discussion. The attitudinal data produced was subjected to a series of statistical tests to determine which of the attitudes revealed could be quantified significantly in terms of public opinion. The most significant responses related to the proximity of wind turbines to respondents' homes with the proposition that wind turbine designers should seek community input of the highest significance. Respondents also indicated a preference for traditional turbine structures that blended in with the landscape and remained out of sight. Respondents' personal perception of land use change regarding wind power near them was mostly significant relative to respondent age with younger respondents tending to be more accepting of wind turbine land use whilst older respondents objected. Living place was also found to be significant with urban respondents more accepting of wind power than rural ones. Fundamentally respondents although polarised for or against on certain issues, all shared a wish for more public input and participation in local land use for wind power.

The wind is an uncontrollable primary resource, although its energy can be stored. This fact can be used for the design of strategies for a better management of electric power networks. An option for achieving this goal is to install Battery Energy Storage Systems (BESS) in the wind farms (WF). When dealing with WFs combined with BESSs the most important is to manage the power production in order to meet the requirements of the network or those related with the owner of the plant. Both challenges constitute an optimization problem. This paper proposes an Evolutionary Algorithm (EA) to solve it, where a fitness function must be maximized under the consideration of certain constraints. The fitness function depends on the target of the power production, which may be either to help the network become more stable or to maximize the profit, assessing each scenario and accepting the best one. The constraints of the optimization problem are related to the levels of the BESSs: the maximum power transferred to or from it and the output power of the plant.

In order to make better use of wind resources and reduce abandoned wind and improve capacity of grid accepting wind power ,this paper studies the feasibility of storing abandoned wind based on using the PHS(Pumped Hydro System). The paper has constructed model of Wind – PHS co-generation system based on operating characteristics of various types of power. Under the constraints of system demands and the technical characteristics of various types of power, the model use the minimum total operation cost of the system as the objective function, then use real coding genetic algorithm simulation to solve the problem. The results show that the use of pumped storage power station can not only reduce the abandoned wind, and the economic benefits of storage abandoned wind are better than the economic benefits of without wind abandoned. At last with evaluation and factors influencing the analysis, the conclusion that the optimal capacity of pumped storage power station in the system is expected to providing a reference which can help for the rational allocation of resources.

To solve the actual task of assessing additional flexible generation needed to smooth variable renewable energies (VRE) disturbances in the Power Systems worldwide the original method for statistical processing of wind and solar PV generation variability data was proposed in the article. The proposed method allows processing the historical data of VRE day-by-day and hour-to-hour generation and assessing the levels of potential disturbances this type of generation could cause. These disturbances should be smoothened in the Power System by others, usually conventional generators at least to ensure grid stability and electricity quality. Currently, at the stage of the power systems starts transformation, the sources of power system flexibility basically are the power plants whose individual flexibility is characterized by three dimensions: adjustability, ramping and lead time. Lack of flexible generation causes VRE curtailments that negatively affect economic efficiency of such clean generation. From the other hand, the improvement of existing power plants flexibility requires an essential investments and time to retrofit them, and because of that the important question - what is the required level of power system flexibility is needed to smooth current and future VRE generation. The results of statistical data processing for wind and solar PV hour-by-hour power output changes allow accepting the hypothesis about the normal distribution of these data sets. The article presents the key parameters of theoretical normal distributions are calculated for wind and solar PV data sets for 2019 and 2020 as a whole, and also for winter and summer seasons, which allow obtaining a more precise assessment of variability levels for renewables, especially for solar PV hour-by-hour generation changes. The assessments obtained in the article also could be used as the first step for more efficient management of the electricity market, for instance, forecasting the required level of flexible generation or ancillary services market for intraday power system balancing.

In recent years, China’s new energy has developed rapidly, and at the same time there have been serious problems of abandoning wind and abandoning light. In order to better solve the problem of new energy consumption, China officially implemented the renewable energy quota system in January 2019. Therefore, based on the current situation of new energy consumption in China, this paper first analyzes the impact of renewable energy quota policy from two aspects: capacity efficiency and grid connectivity effect, and then based on tapping local energy potential, accepting trans-regional power transmission, and optimizing outside the region. The corresponding new energy consumption strategy is proposed in the power transmission curve. Finally, based on the time series production simulation model, an empirical analysis is made on the consumption situation of a certain provincial power grid under different strategies in 2020. This paper provides a reference for promoting the proportion of new energy consumption in China.

The notion of reducing our environmental footprint, minimizing leaks and spillages, and identifying operational efficiencies is nothing new. We have been addressing these issues for years. Sustainability, however, has gained a higher profile recently, especially since the 2015 United Nations Framework Convention on Climate Change accord and the evolution of alternative energies. It came, therefore, as a pleasant surprise to review an extraordinary wealth of well-written papers relating not only to this topic, but to all manner of fascinating engineering issues. Let me back up a bit. For 6 years, I have provided commentary concerning matters relating to reservoir simulation. This was often illuminating, but my primary interest has always been in full-field modeling: coupling our models for flow in porous media, wellbore, network, and to facilities. I firmly believe that unified full-field modeling can furnish benefits both operationally and economically. In accepting the challenge to write this, however, I did not expect to encounter the extraordinary breadth of topics covered. Saying that, one clear thread did emerge from the articles reviewed - namely reliability, emissions control, and energy saving and monitoring, all of which relate to sustainability in one way or another. Novel methods for valve- failure prediction, pipeline coatings, floating storage tank roof optimization, and the use of drones (from spray painting to surveillance) along with robots for unmanned installations were all topics represented in the papers provided me. Paper SPE 198165 is an informative overview of alternative fuels and how these may affect Middle East production; however, this should appeal to a wider readership because it reviews alternative energies nicely. Paper IPTC 19775 provides a means to better quantify separator shrinkage, which can result in errors in stock-tank rates up to 20% (essential if one is to quantify unit energy consumption accurately). Paper SPE 197759 proposes methods for energy savings. These papers represent but a small sample of a broader swath of articles from the past year relating to this catch-all term “sustainability.” Recommended additional reading at OnePetro: www.onepetro.org.

The legitimacy and effectiveness of the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) depends on problem-adequate listing decisions. Decisions are frequently highly controversial, because they commit the member states to imposing trade restrictions on listed species. We examine whether—and how—CITES' impressive institutional apparatus deprives the member states of their bargaining power and empowers actors who can make reasoned arguments on the merits of a listing decision. For this purpose, we demonstrate theoretically that appropriately designed decision-making procedures can diminish stake-holders' opportunities for exploiting their bargaining power and provide room for reason-based deliberation. Subsequently, we explore member states' and other stakeholders' incentives, created by the CITES listing procedure, for refraining from bargaining and accepting scientifically sound decisions. Finally, we examine three recent controversial listing decisions as examples of the actual operation of the listing procedure.

What are the consequences of Syriza coming to power in Greece in 2015? Did it become a new Weimar Germany for the future Europe? In this article we test the hypothesis that winning two consecutive parliamentary elections in 2015 and forming a government contributed to a farther institutionalisation of this party within the rules of Greek democracy. This article is based on data from the Greek Ministry of Interior and the website of the Greek parliament. This text aims at presenting the process of transformation of Syriza - a radical, left-wing, anti-establishment and anti-austerity party into a governmental entity, pro systemic and accepting the principle of the democratic state of law. All this was due to the establishing of the governmental coalition with ANEL, a nationalist party; social-economic reforms; the reform of the electoral system for parliamentary elections; the proposal of a constitutional reform and the ending of the nearly 30-year dispute with Macedonia. The electoral failure during the parliamentary elections on the 7th of July 2019 finishes a 4-year governance of Syriza and enables us to try to evaluate this experiment for the first time. A key finding of our investigation is the need to highlight the respect for the democratic rules by Syriza during its government and its further institutionalisation as one of the main groupings of the contemporary party system in Greece.

Nickelson (1986; Can. J. Fish. Aquat. Sci. 43: 527–535) was unable to reject the null hypothesis (Ho) of density-independent marine survival rate for Oregon coho salmon (Oncorhynchus kisutch) when wild, private hatchery, and public hatchery stocks were analyzed separately. Thus, even though there appears to have been no consistent increase in adult abundance in recent years in spite of large increases in smolt abundance, Nickelson's analysis does not support the alternative hypothesis (HA) of density-dependent marine survival. Some fishery managers are using Nickelson's results to support proposals to increase smolt production further. I calculated statistical power for these cases, i.e. the probability that the null hypothesis of density-independence could have been rejected, even if marine survival were truly density-dependent. Power was below 0.19 for all cases, which meant that Nickelson (1986) had at least an 81% chance of making a Type II error (incorrectly accepting Ho), if Ho was actually false. Therefore, Oregon fishery managers should be cautious about making decisions on increased smolt production based on current data; they run a high risk of mistakenly assuming density-independent marine survival. More generally, managers should not take action based on a failure to reject a null hypothesis unless power is high.

The purpose of this study is to empirically investigate if the municipal decision on wind power development can be explained by a model including socioeconomic variables and proxies for the natural environment, using a pooled cross-section data set for Swedish municipalities for the period 2010-2019. The study poses the question whether politicians' decisions-making can be explained by socioeconomic factors. In order to analyse the approving or denying of wind power development in Swedish municipalities, three models are used: the linear probability model, the probit and the logit model. The results show that the Green political party (positively affecting wind power development) and that the unemployment rate, income, population density, protected areas and the affiliations with the Sweden Democrats (negatively affecting the approval rate), has a statistical significant effect on the permissionprocess. Installed capacity of wind power plants seemingly have no impact. Our findings suggest that the municipal decision making is less random than the critics of the municipal veto proposes.

This study examines different meanings attached to and practices adopted during Swedish local consultation processes on offshore wind power projects. It analyses the role played by those processes in a democratic planning context, as well as the ways in which they are implemented. It also identifies overarching process models. The study is informed by theories on democracy, planning, participation, communication, and media. The empirical material comprises three case studies, each examining experiences of local consultation processes for wind power projects that led to differences in local reception. Methodologically, the study triangulates analyses of semi-structured interviews, documents and news articles. The results show that, in a Swedish context, the role of local consultation processes is to create legitimacy and trust in the process and planning decisions. The complex dynamics become evident in the different forms of participation, knowledge generation, and communication employed during the consultation. This is shown to be the result of various democratic and planning attitudes to locally-situated interests and knowledge, which in turn lead to differing views on local understanding for and acceptance of project proposals. The study develops three schematic models that correspond to different types of consultation processes. An important conclusion is that the content and form of local consultation processes depends on the agency of several actors on different scales. They are not simple pre-designed by project planners, but the result of a far more complex interaction between a host of local actors, including officials, local media, and local communities. The categorisation of different local consultation processes could contribute to awareness about the implications of various ways of working with large-scale projects from local perspectives.
I den här avhandlingen undersöks lokala förankringsprocesser med ett särskilt fokus på havsbaserade vindkraftsprojekt. Diskussionen uppehåller sig vid frågor om förankringsprocessens roll i en svensk planeringskontext, samt hur olika utformningar av processen kan påverka det lokala mottagandet. Studien visar att förankringsprocesser ytterst handlar om legitimitet och tillit. I praktiken förekommer en stor variation, komplexitet och dynamik i lokala förankringsprocesser. Det yttrar sig bland annat genom olika former av deltagande, kunskapsbyggande och kommunikation. Centralt i resonemangen är demokratiska och planeringsmässiga förhållningssätt till platsbundna intressen och kunskaper. På så sätt tydliggörs skillnader i synen på förståelse och lokal acceptans avseende ett projektförslag. Genom studien urskiljs också tre schematiska förankringsmodeller som belyser sådana skillnader. Förståelse för lokala förankringsprocesser har betydelse inte minst avseende påverkan på lokal acceptans för storskaliga projekt.

Sveriges regering har tagit fram en nationell planeringsram för vindkraft som inkluderar 30 TWh installerad effekt år 2020. Negativa attityder mot vindkraft kan dock bromsa upp och hindra specifika vindkraftsprojekt, vilket skapar en utmaning för att uppnå målen. En problematik för vindkrafts­projektörer i Sverige är att även om majoriteten av lokalbefolkningen är positivt inställda till en etablering, kan det vara tillräckligt att en person agerar rättsligt för att ett projekt ska fördröjas eller hindras. Motstånd mot vindkraft baseras ofta på subjektiva uppfattningar, vilket innebär att det är svårt att hitta en generell lösning för att öka acceptansen bland lokalbefolkningen. Ibland baseras motståndet på den lokala påverkan en vindkraftsanläggning förväntas medföra medan det i andra fall snarare är ett motstånd mot de som driver ett projekt eller det sätt projektet genomförs på. Denna studie syftar till att kvalitativt undersöka hur lokalbefolkningens acceptans till vindkraftsprojekt påverkas av kommunikationen i planerings- och prövningsprocessen, samt identifiera åtgärder som kan öka acceptansen för nyetableringar av vindkraft. Detta har utförts med hjälp av intervjuer med projektörer, myndigheter och konsulter som delgivit sina tidigare erfarenheter från olika vindkrafts­projekt. Informationen har sammanställts och kopplats till teorier kring attityder och kommunikation för att sedan resultera i en rekommendation för projektörers framtida arbete. Studien har resulterat i bland annat ett antal faktorer som kan påverka acceptansnivån och attityderna hos lokalbefolkningen, som därmed är viktiga för projektören att ta hänsyn till i kommunikationen med de närboende. En vindkraftsetablering innebär för många en förändring av närområdet och kan skapa en känsla av oro för hur etableringen ska påverka människor och miljö. En etablering kan även skapa en känsla hos de närboende av att de inte har kontroll och bestämmanderätt över sin närmaste omgivning och livssituation. Oro samt känslan av att sakna kontroll kan skapa negativa attityder och bör därför fokuseras på under projektet. Ett sätt att erbjuda lokalbefolkningen kontroll är att involvera dem i projektet samt förklara samråds- och tillståndsprocessen. Ett sätt att stilla oro är att delge de närboende saklig och korrekt information kontinuerligt under hela projektet. Det är viktigt att involvera lokalbefolkningen för att de inte ska känna sig åsidosatta, men om lokalbefolkningen involveras är det viktigt att deras åsikter har en reell effekt på etableringen. Människor litar på information de får från en tillitsfull person. Därför är det viktigt att projektören inger förtroende och vinner tillit från lokalbefolkningen. Detta kan fås genom att ha en ärlig, öppen och respektfull kommunikation. Det är även viktigt att projektörer visar att de tar hänsyn till och lyssnar på lokalbefolkningens åsikter och oro, oavsett om dessa är relevanta för tillståndsprövningen eller inte. Det är viktigt med en tidig och proaktiv kommunikation då studiens resultat påvisat att det är svårt att förändra negativa attityder. Om människor bygger en negativ attityd på felaktig information, rykten eller spekulationer är det svårt att ändra dessa attityder i efterhand. Därför är det viktigt att aktivt informera människor tidigt i processen. Projektören bör tidigt i processen kartlägga intressenter och deras eventuella oro i syfte att sammanställa en kommunikationsplan. Resultaten visar tydligt att ett utställningssamråd har större förutsättningar att skapa en lokal förankring för ett projekt än ett presentationssamråd. Vid ett presentationssamråd är det svårt för alla människor att komma till tals och ställa sina frågor eller lämna synpunkter. Vid en utställning sker en dialog mellan projektörer och närboende, vilket innebär att samtalet kan fokusera på den enskilde individens oro. Risken för feltolkningar och missförstånd minskar då projektören kan anpassa dialogen till den närboende. Övriga åtgärder som kan öka acceptansen för vindkraftsprojekt är bland annat ekonomisk ersättning och fältbesök. Ekonomisk ersättning kan ge en individuell tillfredställelse. Fältbesök och liknande åtgärder kan ge de närboende nya erfarenheter av vindkraft, vilka kan stilla lokalbefolkningens oro och därmed påverka attityden mot specifika vindkraftsetableringar positivt.
The Swedish government has established a national planning framework for wind power, including a goal of 30 TWh of installed capacity by 2020. It has however been proven difficult to reach these goals since negative attitudes towards wind power projects can hinder the development. One main issue is that even though the majority of the local community is positive to a wind power establishment, it can be enough that one person take legal action against it for the project to be interrupted. Resistance towards wind power is often subjective which means that it is difficult to find a general solution to increase the acceptance among the local community. People often resist the local impact wind turbines might cause, but the resistance could also be towards those who carry out the project or how the project is conducted. This study aims to qualitatively investigate how communication throughout the planning- and permission process affect the level of acceptance among the local community, as well as to identify measures which can raise the acceptance for wind power projects. Interviews have been conducted with project planners, authorities and consultants in order to gather their experiences from previous projects. This information has been related to theories regarding attitudes and communication and has resulted in a recommendation of how future projects should be conducted in order to raise the local acceptance. The study results in several factors that affect the level of acceptance and the attitudes among the local community. These factors are important for the project planner to take into account when communicating with the public. A wind power establishment is for many people a huge change in the surroundings, and can create a feeling of worry and anxiety related to how the establishment will affect humans and the environment. A project might also cause a feeling of not being in control. These two feelings can create negative attitudes towards a project. One way to create a feeling of control is to involve the local community in the project and to explain for them the process of planning a project and applying for permission. In order to ease worries, the project planner should share objective and accurate information. People tend to trust the information they receive from a person they consider trustworthy. Therefore it is important for the project planner to act in a trustworthy manner, for example by being honest and to use a transparent and respectful communication. It is also important that the project planner listen to the public’s opinions and worries, even though they are not relevant for the permission process. The study proves the difficulty of changing already negative attitudes, which emphasise the importance of an early and proactive communication. If people create a negative attitude based on false information, rumours or speculations, it is hard to change their attitudes afterwards. Therefore it is important to map actors in the community and their potential worries, with the purpose to construct a communication plan. The results clearly indicate that a consultation meeting in the shape of an exhibition instead of a presentation has a higher potential for creating a local acceptance towards a project. With only a presentation not everyone will have their saying. An exhibition enables a dialogue between the project planner and individual inhabitants where opinions and questions can be more easily communicated between the parties. The project planner can also easily adapt the dialogue to decrease the risk of misperceptions and confusions. Other measures that can increase the level of acceptance are economical compensation as well as field trips, where the inhabitants can create their own opinion of the impact from wind turbines. It can ease worries and thereby create positive attitudes towards wind power projects.

The global climate threat has intensified Sweden’s ambitions to build wind power stations. This thesis explores the planning of, and opposition to, wind power in the inland rural and forest regions of Sweden. It is in these autonomous communities that the plans are implemented and the aim of the thesis was to, from a local perspective, understand and analyse the planning and acceptance challenges that large-scale wind power development faces in places that are both sparsely populated and have good wind conditions. This thesis is based on qualitative methods and was conducted as two studies. The case study area comprises four municipalities in Dalarna County. The first study analyses the planning and establishment process in three municipalities using interviews and an analysis method called process tracing. The second study analyses one wind power establishment, in which the interviews form the basis for a discourse analytical approach. One striking finding highlights the relationship between the global and the local. Global environment and energy aspects are absent in the local process, and wind power becomes a technical land issue that clashes with other local land interests. Another finding of the study reveals that planning for wind power establishment follows a rational planning tradition. The feelings and memories of the individual – different views regarding the landscape – play a background role in the formal permit process, while measurable observable conditions have a more prominent role. Wind power developers thereby acquire a more significant position than what they probably would have had if the planning had included local residents’ views on wind power in the landscape at an early stage.

AbstractDifferent classes of automata on infinite words have different expressive power. Deciding whether a given language$$L \subseteq \varSigma ^\omega $$L⊆Σωcan be expressed by an automaton of a desired class can be reduced to deciding a game between Prover and Refuter: in each turn of the game, Refuter provides a letter in$$\varSigma $$Σ, and Prover responds with an annotation of the current state of the run (for example, in the case of Büchi automata, whether the state is accepting or rejecting, and in the case of parity automata, what the color of the state is). Prover wins if the sequence of annotations she generates is correct: it is an accepting run iff the word generated by Refuter is inL. We show how a winning strategy for Refuter can serve as a simple and easy-to-understand certificate to inexpressibility, and how it induces additional forms of certificates. Our framework handles all classes of deterministic automata, including ones with structural restrictions like weak automata. In addition, it can be used for refutingseparationof two languages by an automaton of the desired class, and for finding automata thatapproximateLand belong to the desired class.

As plug-in electric vehicles (PEVs) grow in popularity, there is increasing research interest in the interaction between PEVs and the electric grid. Much of the previous work in the literature relies on an assumption that PEV charging will be scheduled, and that the duration and magnitude of charging loads can be modulated to suit the needs of the utility and the system operator. While access to the data or owner input necessary for charge scheduling and management might be technically feasible today, it is unclear whether vehicle owners will be amenable to providing these data or accepting utility control of their charging choices. Because of these uncertainties in the future relationship between electric utilities and PEV owners, this study seeks to examine the market effects of vehicles in the absence of the additional data utilities would need to realize these alternate, “optimal” PEV charging scenarios. In particular, this study focuses on quantifying the potential uncertainty in vehicle charging loads on an energy and power basis. Monte Carlo methods were applied to vehicle trip data from the National Household Travel Survey (NHTS) to generate simulated driving profiles for individual vehicles. Using these profiles, six PEV fleet sizes were studied, ranging from 1,000 to 500,000 vehicles, to determine whether fleet size had a linear effect on the stochasticity of vehicle charging loads. Following the Monte Carlo simulations, these loads were examined independent of and compared to net load (load minus wind generation). Results from the Monte Carlo simulations indicate that even for the largest PEV fleet sizes studied, variability in average charging loads is on the order of 10 MW, less than 0.2% of the magnitude of charging load for those fleet sizes. In comparison with electricity demand in the Electric Reliability Council of Texas’ (ERCOT) operating area, these charging loads represent a 1% increase above typical summer peak loads. Unfortunately, while the relative increase in demand is small, the timing of peak charging load is nearly coincident with summer peak demand. The simulation approach was validated by comparing the results against empirical vehicle charging data collected by the Pecan Street Research Consortium from households in Austin, Texas. Simulated and empirical vehicle charging trends showed generally good agreement, with similar charging times but slightly different charging durations. The alignment between the two charging profiles indicates that the simulation methodology applied here with NHTS travel data can be used to predict electric load for vehicle charging when empirical historical charging data are not available.
