Sahel, Wissal. „Participatory design to support power grid operators in control rooms“. Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASG022.
Der volle Inhalt der QuelleSafety-critical control room technology poses multiple challenges for operators, especially with respect to increasing workload, information overload, and lack of situation awareness. My review of the research literature on control room productivity shows that today's technology was developed with limited operator involvement in the design process, which has led to tools that target specific problems while neglecting the overall workflow. We conducted a two-year participatory design project with RTE (the French power grid) operators to better understand the problems operators face. Key needs include improved information overviews and support for operators' secondary tasks, e.g., tracing information and prioritization. We used a generative theory approach to design StoryLines, an interactive timeline that helps operators collect information from diverse tools to create an overview, record reminders and share relevant information with the next shift's operator. The combination of participatory design and generative theory let us explore operators' existing note-taking practices about grid status and expected future events, which informed the design of StoryLines. We conducted two comparative structured observation studies to assess the strengths and weaknesses of StoryLines and to suggest directions for future research

Der volle Inhalt der QuelleThe concept of multisource system (with energy storage) with integrated and optimised energy control it’s also knows as a virtual power plant. These types of power plants are constituted from different class of generators which can be associated with different types of energy storage systems. From the point of view of network managing, a virtual power plant must behave as a classical power plant. It must participate to the ancillary service and also the manager has to know 24h ahead the quantity of electrical energy he can produce. The multisource systems associated with storage system exists already in isolated sites, many studies and experimentations have been developed for isolated networks using diesel generators associated with wind turbines and flywheel energy storage systems or using batteries. The objective of this project is to increase the penetration rate of the wind power plants to decrease the fuel consumption. The mains problems of this system are the choice of storage system and the determination of the supervisory control in order to optimize the energetic consumption and to assure the network stability

Der volle Inhalt der QuelleThe limited reserves of fossil fuel and the pollution gases produced pave the way to promising alternativeRenewable Energy Sources (RESs) such as Solar Energy Sources (SESs) and Wind Energy Sources (WESs).SESs and WESs are freely available and environmentally friendly. However, RESs are intermittent in nature.Therefore, the smoothing of power fluctuations by storing the energy during periods of oversupply and restore it tothe grid when demand becomes necessary. Accordingly, Energy Storage Systems (ESSs) can be appropriatelyused for this purpose.Using several energy sources for constructing HPSs alongside with ESS will require an energy managementstrategy to achieve minimum HPS cost and optimal balance between energy generation and energy consumption.This energy management method is a mechanism to achieve an ideal energy production and to conveniently satisfythe load demand at relatively high efficiency.In this thesis, a Hybrid Power System (HPS) including Renewable Energy Sources (RESs) such as main sourcescombined with Gas Micro-Turbine (GMT) and hydrogen storage system such as Back-up Sources (BKUSs) hasbeen presented. The aim of this hybridization is to build a reliable system, which is able to supply the load andhaving the ability to store the excess energy in hydrogen form and reuse it later when demanded. Consequently, thestored energy at the end of each cycle will be zero and a minimum generated power cost is achieved. In addition,partial shading problem of Photovoltaic (PV) panels is comprehensively studied and a new solution based on simpleswitches and Fuzzy Logic Control (FLC) integrated into dSPACE electronic card is created. Consequently, a realtime PV panels reconfiguration and disconnecting shaded ones is performed and minimum power losses isachieved. Then, the PV panels are connected to a Proton Exchange Membrane Electrolyser (PEM ELS). Theemitted temperature by the PV panels is transferred to the endothermic element PEM ELS. Consequently, anefficiency enhancement of the hybrid system PVPEM ELS is realized

Der volle Inhalt der QuelleA hybrid power system is studied in this thesis for the distributed generation based on renewable energy resources and energy storage systems in microgrid applications. It consists of a wind generator as primary energy source, super-capacitors as fast-dynamic storage system, fuel cells and electrolyzers as long-term storage system in hydrogen. They are all connected to a common DC bus and an inverter is used for the connection of the whole system to the grid. In this thesis, we have presented the system modeling, the control design including the power balancing and energy management strategies. This hybrid power system can finally supply controllable smooth powers as most conventional power plants. The performances have been tested in numerical simulations and also on an experimental test bench. As result, it is able to provide ancillary services to the microgrid. The main scientific contributions of this thesis are: the use and the adaptation of the graphical tools for the modeling of complex systems and their design; the design and the experimental implementation of real-time emulators in order to reduce the time and the cost of an experimental platform; the proposition and the validation of two power balancing strategies for the DC-bus voltage regulation and the grid power control and finally the proposition of energy management strategies for the active wind generator to ensure the energy availability

Der volle Inhalt der QuelleThis research work deals with two topics conditioning the large scale development of wind turbines into electrical grids. The first is devoted to the development of new algorithms for the control of Doubly Fed Induction Machine (DFIM) based wind energy conversion systems. Two direct current control strategies have been proposed and are based on the hysteresis square areas (HZCA) and hysteresis circular areas (HZCI). Both strategies apply an appropriate voltage vector to control the active and reactive powers delivered to the grid, and also, to balance the voltages of the inner DC bus converter. Simulation and experimental results show that the HZCI strategy is better than HZCA in terms of output voltage waveforms and harmonic contain.The second topic is dedicated to the active and reactive powers supervision in a wind farm in order to supply prescribed power references from the grid operator. This supervision is ensured by a centralized algorithm that distributes power references between wind turbines in a proportional way. These references are calculated according to the maximum production capacity of wind turbines. An analysis of the power flow in the DFIM based wind energy system has been made to identify the (P, Q) characteristic and to calculate limits in terms of reactive power compensation. The local power management of each wind system has been developed allowing the powers distribution between the stator of the DFIM and the grid side converter by considering several operating modes of the wind generator
