REGIONAL INSERT OF THE BELO MONTE HYDROELECTRIC PLANT AND TERRITORIAL GOVERNANCEINSERCIÓN REGIONAL DE LA PLANTA HIDROELÉCTRICA BELO MONTE Y LA GOBERNANZA TERRITORIALRESUMOA relação entre a implantação de grandes projetos de investimento (GPI), em especial, os grandes projetos hidrelétricos e as populações locais, tem se constituído, um aspecto recorrente, desde a década de 1970, no âmbito dos debates sobre o desenvolvimento regional há décadas. A literatura técnica e científica sobre as hidrelétricas tem revelado não somente a sua natureza impactante, evidenciando as transformações territoriais delas advindas, como também o caráter de enclave e, mesmo, de empreendimentos de múltiplos propósitos no que respeita ao desenvolvimento regional. A natureza de enclave aponta a evidente subordinação do conjunto de interesses regionais ao cumprimento de um fim único: a geração de energia elétrica para abastecer demandas espacialmente distantes e potencializar os processos de acumulação de capital extra-regionais, com mínimos benefícios para a região de implantação. O presente trabalho tem assim por objetivo refletir sobre os processos de inserção regional de usinas hidrelétricas na Amazônia e a governança territorial implementada, considerando os aspectos mencionados acima e sua influência nas concepções de planejamento que orientaram a construção da usina hidrelétrica Belo Monte na década de 2011 a 2019.Palavras-chave: Hidrelétrica; Belo Monte; Amazônia.ABSTRACTThe relationship between the implementation of large investment projects (GPI), in particular, large hydroelectric projects and local populations, has been a recurring aspect since the 1970s, in the context of debates on regional development for decades. The technical and scientific literature on hydroelectric dams has revealed not only their impactful nature, highlighting their territorial transformations as well as the character of an enclave and even of multi-purpose ventures with regard to regional development. The nature of the enclave points to the evident subordination of the set of regional interests to the fulfillment of a single purpose: the generation of electric energy to supply spatially distant demands and to potentiate the processes of accumulation of extra-regional capital, with minimal benefits for the region of implantation. The present work aims to reflect on the processes of regional insertion of hydroelectric plants in the Amazon and the implemented territorial governance, considering the aspects mentioned above and their influence on the planning concepts that guided the construction of the Belo Monte hydroelectric plant in the 2011 decade to 2019.Keywords: Hydroelectric Power Plant; Belo Monte; Amazon.RESUMENLa relación entre la implementación de grandes proyectos de inversión (GPI), en particular, grandes proyectos hidroeléctricos y poblaciones locales, ha sido un aspecto recurrente desde la década de 1970, en el contexto de debates sobre desarrollo regional durante décadas.

The introduction of battery energy storage systems and the subsequent transfer of electricity is a very important task, which is solved in different countries in different ways, based on the types of products that can be provided by battery energy storage systems. The analysis of the structure of generating capacities in the United Electric Power System of Ukraine shows a significant deficit of shunting capacities, among which today there is thermal generation, which has a significant level of wear of the main generating equipment and hydroelectric power plants. Based on the above, it would be logical to assume that with the launch of a new model of the electricity market; market segments will be formed in which price signals will be attractive for investment in new shunting capacity. However, the formation of such signals is limited by the establishment of upper price indices on the additional service market and market day ahead. Thus, to simulate the operation of battery energy storage systems, the additional service market was chosen in which the system operator purchases services from additional service providers. Modeling the operation of battery energy storage systems for the provision of additional services is a multi-criteria task that takes into account both the technical features of the battery energy storage systems and the relevant price indices that have been formed for each type of service. The paper considers the possibility of providing services from the automatic reserve of frequency recovery and the provision of balancing services. Based on statistical data on the additional service market of the integrated power system of Ukraine, developed a mathematical model to assess the effect of the use of battery energy storage systems to provide services for primary, secondary and tertiary frequency control. The relationship between the price indices of additional service market and technical and economic characteristics of the battery energy storage system are determined. The target function is offered in the mathematical model of operation of the battery energy storage systems, which takes into account the reduced costs for the accumulation of a unit of electricity, maintenance costs and income from the provision of services on the additional service market.

Abstract Comparative analysis of methods of obtaining electricity from a renewable energy source is carried out. Various designs and op-tions for small hydroelectric power plants have been proposed. Positive and negative factors of structures under consideration and their impact on the environment are analyzed. The main characteristics of the flow (speed, head) for the choice of the optimal variant of hydroelectric power plant have been determined. Three variants of impellers for free-flow hydroelectric power plants are proposed with a comparison of the efficien-cy of each variant. An analysis was carried out and an impeller based on a Darrieus rotor was selected for further research. Simulation was performed in the Flow Simulation program. The initial data for the design of Darrieus rotor operating in a liquid were the diameter and width of the impeller. The calculations involved a rotor with straight and swirling blades. The swirling blades rotor is self-starting. In the course of the calcula-tion, the speed of the liquid flow approaching the rotor and the rotor speed were changed. As a result of cal-culation, the value of the positive moment for self-starting was determined, which occurs at an incident flow velocity of at least 1.3 m/s.

The Durance River is a highly regulated, gravel-bed river with a naturally high fine sediment load in southern France. EDF operates eight dams along the regulated main stream channel (218 km from the Serre-Ponçon Dam to the confluence with the Rhône River), that divert water to 16 hydroelectric power plants via a canal. Flow regulation has contributed to fine sediment accumulation (clogging) in the Durance River. In addition to a recent increase in minimum flows has implemented targeted water releases at four out of eight dams to simulate floods and reduce clogging to restore river function for fishes and invertebrates, The timing of these releases is defined for each dam based on the spawning period of target fish species. During the release, TSS, O2, T, H, and conductivity are measured continuously. Before and after each release, clogging (superficial/interstitial) is measured. This monitoring program showed that several of the releases were not effective on surface clogging inducing a loss of water or resulted in effects contrary to those sought, although this was not reflected in the biological results. These results indicate that two parameters must be taken into account to determine a priori the need to carry out releases: the hydrology observed during the year and the initial level of clogging. Artificial flood releases are increasingly being used a management tool to mitigate hydropower impacts on river hydromorphology and ecology. This experimentation shows that it is necessary to carry out these types of operations in an adaptive management context. At this time, the results obtained do not lead to clear conclusions regarding their efficacy, mostly as a result of strong interannual variation in hydroclimatic conditions, which have a strong influence on initial conditions and resulting outcomes. Furthermore, it is important to incorporate this field measurements and not rely solely on turbidity gauging stations to evaluate efficacy.

The article describes run-of-the-river hydroelectric power plants. The authors specify the importance of performing technical and economic calculations in justifying the large-sized units of the water-supplying channel of a run-of-the-river hydroelectric power plant: turbine pits and suction (discharge) pipes. The study shows that the amount of construction work and the total cost of building a hydroelectric power plant depend on the size of these water supply units. The research objective is to analyze the validity of establishing the main dimensions of the suction pipes for modern technical and economic conditions. The researchers use the discounted income method. The calculations are performed for a hydroelectric power plant with an elbow suction pipe. The analysis of how the operating conditions of a hydroelectric power plant influence the savings of construction resources is carried out. The analysis shows that saving construction resources by reducing the length of the suction pipe is justified if the hydroelectric power plamt is designed to work only at peak power loads. For hydroelectric power plants operating at semi-peak or base power loads, the additional construction costs would be appropriate if leading to the decrease in pressure loss and to the increase in electricity generation.

Hydropower has sufficient resources available and is actively promoted by Governments as part of their energy matrix, but its development is constrained by the difficulty of addressing location particularities, including technical features such as geology or hydrology, and institutional features such as social acceptance, environmental constraints and the regulatory framework. Project results emerge from the interactions of these Inherent Features and the Project Architecture and do not always meet stakeholders' expectations, leading to deficient project results and lost value. This thesis proposes a methodology for prototyping projects to reflect these particularities and inform project shaping and decision-making early in the process. The proposed methodology was built on three systems engineering and project complexity frameworks, and lessons learned from four case studies. Its contribution to hydropower development is related to (i) the incorporation of systems evolution over time on the development process, (ii) the identification and management of relationships among the various decomposed elements of the development, (iii) the identification of emergent properties from the interactions among all features, (iv) a prototype for developers to optimize or search for project architectures that meet stakeholders objectives while complying with restrictions, (v) the delivery of unbiased information for decision-makers, (vi) the opportunity of stakeholders to participate in the project shaping in a continuous fashion, and (vii) the delivery of a tool for the implementation team to evaluate and challenge changes to the project during construction. The usage of this methodology does not guarantee the avoidance of errors or unforeseen project outcomes, but it does reduce the chance for unknown risks emerging from the interactions of the evaluated features.

The Turkish TSO (TEIAS) has been leading a project that aims the synchronous interconnected operation of the Turkish Power System and the ENTSO-E CESA (former UCTE) System. For this purpose, this study concentrates on the specific problems related to the electromechanical systems of large size hydroelectric power plants regarding low frequency inter area oscillations, which are prone to occur once the interconnected operation is established. The expected frequency of inter area oscillations after interconnected operation is close to 0.15 Hz, which is in the frequency range of the speed governing structures of turbines, as explained in the first two sections of the thesis. In the third section, the nonlinear turbine governor model used throughout the study is explained. In the following part, the governor parameter tuning study with regard to the defined performance objectives is explained. Afterwards, the effect of the retuned governor settings of the sample hydroelectric power plants on a simple multi machine power system is shown. Following that, the system wide effect of removing the sources of negative damping, which are strongly dependent on the governor settings of the major hydroelectric power plants of the Turkish Power System, is shown. In the final part, conclusions are made on the operation of the hydroelectric power plants regarding the frequency stability of the system after synchronous interconnected operation of the Turkish Power System and the ENTSO-E CESA System.

This thesis examines the influence of different degrees of serial correlation in the streamflow records on optimal operation of a hydroelectric reservoir. This thesis also investigates the practical aspects of choosing different decision variables, considering effects on ease of implementation, total benefit, and actual use for real-time operations. Stochastic dynamic programming was used to optimize the long-term operation of a hydroelectric project with a single reservoir. Reservoir inflows were analyzed using monthly flow record for 58 years with the assumption that monthly inflows are either perfectly correlated, uncorrelated, or partially correlated. Reservoir level change and powerhouse discharge were considered as alternative decision variables for each of the three cases of inflow serial correlation. The optimization results were then examined and compared to determine the significance of the choice of decision variables and to explore the effects of inflow serial correlation on practical operating decisions which might be based on the results of the optimization. It was found that (1) Case 2 in which inflows were assumed perfectly correlated and Case 3 with partially correlated inflows produce, respectively, highest and lowest total expected return, (2) the difference in total expected return between cases depends largely upon the physical characteristics of the system, (3) the reservoir level change decision case produces more conservative results than the discharge decision case, (4) the results from the reservoir level change decision are easier to use for realtime operation than those from the discharge decision case, (5) different results will be produced with different choice of decision variables.

Las centrales hidroeléctricas, como sistemas reales, tienen un comportamiento no lineal. Con el objetivo de diseñar controladores para turbinas, fue una práctica normal en el pasado considerar o simplificar estos comportamientos no lineales linealizando en un punto de operación las ecuaciones diferenciales que representan la dinámica de la central hidroeléctrica. La principal motivación de esta tesis nace como consecuencia y la necesidad de mejorar y optimizar las respuestas dinámicas de las plantas hidroeléctricas, considerando estos comportamientos no lineales, conduciendo a modelos dinámicos más realistas del sistema de la turbina hidráulica, además, desarrollar y diseñar controladores más eficientes. Esta tesis considera en general el caso de sistemas de operación aislados, este es el caso de una central hidroeléctrica alimentando una carga aislada.
En esta tesis se cubren dos objetivos principales: 1) Profundizar el Conocimiento de los Modelos de Sistemas Hidroeléctricos, 2) Diseñar Controladores a Partir de Modelos Probados.
Profundizar el Conocimiento de los Modelos de Sistemas Hidroeléctricos
Este objetivo consiste en desarrollar un análisis comparativo de diferentes modelos de centrales hidroeléctricas aplicados al control de la velocidad de giro de la turbina, y proponer nuevos modelos. Con este propósito se utilizan parámetros tomados de diferentes centrales hidroeléctricas referenciadas en la bibliografía. Además, se propone la identificación de la central hidroeléctrica de Susqueda (Río Ter, Girona) usando estos modelos previamente refinados. Un paso previo muy importante para el diseño de un controlador es obtener un modelo dinámico de un sistema hidráulico confiable.
Diseñar Controladores a Partir de Modelos Probados
El segundo objetivo es el desarrollo y diseño de controladores de la frecuencia (velocidad de giro) para centrales hidroeléctricas usando técnicas de control no lineal basadas en técnicas de la geometría diferencial y de la función de Lyapunov. En ambos casos los controladores son diseñados a partir de modelos de sistemas hidráulicos no lineales. Los resultados demuestran que usando dos funciones de coste, los controladores no lineales mejoran el comportamiento dado por los clásicos controladores PID entre un veinte y un doce por ciento, y con respecto a un controlador Gain Scheduling la mejora es entre un quince y un doce por ciento.
Hydroelectric power plants, like real systems, have nonlinear behaviour. In order to design turbine controllers, it was normal practice in the past to consider or simplify these nonlinear behaviours by linearizing at an operating point the differential equations that represent the dynamics of the hydroelectric plant. The main motivation of this dissertation was born as a consequence and necessity of improving and optimising the dynamic responses of hydroelectric plants, by taking into account these nonlinear behaviours, leading to more realistic dynamic models of the hydraulic turbine system and to the development and design of more efficient controllers. This dissertation considers in general the case of isolated system operations; it is therefore the case of a hydroelectric power plant supplying an isolated load.
Two objectives are covered in this dissertation: 1) To Deepen the Knowledge of Hydroelectric System Models, 2) To Design Controllers from Well Proven Models.
To Deepen the Knowledge of Hydroelectric System Models
This objective consists of performing a detailed comparative analysis of different existent hydroelectric models applied to speed control and propose new ones. For this purpose real parameters taken from many hydroelectric power plants referenced in the bibliography are utilised.
Moreover, the identification of a hydroelectric power plant on the Ter River (Susqueda) is proposed by using these previously refined models. To obtain a reliable dynamic model of hydraulic turbine systems is an important step prior to the controller design.
To Design Controllers from Well Proven Models
The second objective is the development and design of frequency (speed) controllers for hydroelectric power plants by using nonlinear control techniques based on differential geometry and on the Lyapunov function. For both cases the controllers are designed from nonlinear dynamic models of hydraulic turbine systems. The results demonstrate that using two cost functions the nonlinear controllers improve the behaviour given by classical PID controllers between a twenty and a twelve per cent, and with respect a Gain Scheduling controller the improvement is between a fifteen and a twelve per cent.

This study examines the controversy regarding Hells Canyon on the Snake River, North America's deepest gorge. Throughout the 1950s, federal and private electric power proponents wrangled over who would harness the canyon's potential for generating hydroelectricity. After a decade of debate, the privately-owned Idaho Power Company won the right to build three small dams in the canyon versus one large public power structure. The thesis concludes that private development of Hells Canyon led to incomplete resource development. Further, support of private development led to extensive Republican electoral losses in the Pacific Northwest during the 1950s.

A scheme to streamline the electric power generation profile of concentrating solar power plants of the parabolic trough collector type is suggested. The scheme seeks to even out heat transfer rates from the solar field to the power block by splitting the typical heat transfer fluid loop into two loops using an extra vessel and an extra pump. In the first loop, cold heat transfer fluid is pumped by the cold pump from the cold vessel to the solar field to collect heat before accumulating in the newly introduced hot vessel. In the second loop, hot heat transfer fluid is pumped by the hot pump from the hot vessel to a heat exchanger train to supply the power block with its heat load before accumulating in the cold vessel. The new scheme moderately decouples heat supply from heat sink allowing for more control of heat delivery rates thereby evening out power generation.

Brazilian hydroelectric power plants often use telemetry stations to extract information about the environment. These equipment are usually installed in several strategic spots of rivers that "feed" the reservoir, and are capable of providing important information such as precipitation, river level, and water flow. This paper presents an analysis of Machine Learning applied to the forecasting of spillage occurrences over a set amount of time in a Brazilian power plant. To achieve this goal, telemetry stations' data were utilized together with the plant's operations historical, which provides information about previous spillages, turbines' flows, among others. The Machine Learning approach has shown to be promising in this problem, and the developed model presented the potential to effectively support decisions by helping the operators prepare for significant incoming water flows.
