Full textThe present work deals with the necessary development of a virtual power plant allowing managing energy production systems and promoting renewable energy for the Perpignan Méditerranée agglomeration community (Pyrénées-Orientales, France). First, are presented the worldwide energy context, the state of the art about virtual power plants as well as the proposed approach for managing energy resources. Next, a methodology allowing forecasting the electric load and meteorological parameters, such as both the mean average wind speed and the global solar irradiation, are proposed and integrated as a module in the virtual power plant. Scenarios and energy strategies were developed with the purpose of satisfying the electricity demand, using renewable energy. Storing energy as well as buying or selling on the Powernext market was also considered. Finally, the proposed tool opens the possibility of optimally sizing new production systems. According to both the intensive growth of the electricity market and the greenhouse gas emissions, the developed virtual power plant focuses on improving energy efficiency and favouring environmental protection

Full textThe inherent stochasticity of variable renewable energy sources (vRES) challenges their widespread integration, prompt-ing the emergence of the virtual power plant (VPP) paradigm, which reduces vRES variability through their combined operation with flexible, dispatchable units. As vRES penetration continues to grow, VPPs are expected to expand in portfolio size. However, the portfolio dimension represents only one aspect of the complexity of modern VPPs. These systems also involve factors such as hard nonlinear dynamics, multiple sources of uncertainty, and intricate coupling constraints between aggregated units. Together, these challenges contribute to the evolution of VPPs into large-scale, dynamic systems with complex internal dynamics—referred to here as complex VPPs. A major challenge in the devel-opment of complex VPPs is the need for fast, scalable decision-making tools that can maintain both solution quality and accuracy. To address this, this thesis introduces a two-level, scenario-based, fully stochastic decision-making framework designed to optimize VPP participation in the electricity markets across multiple time stages. The framework is then fully decomposed along both the scenario and spatial dimensions, enabling the creation of a scalable distributed algorithm that guarantees performance, even for mixed-integer VPP models. This methodology is validated through a real-world case study from the French aggregator Compagnie Nationale du Rhône, which manages a complex VPP combining run-of-the-river cascaded hydropower plants, wind, and solar assets. The results show that this complex VPP can enhance vRES integration without relying on conventional storage solutions. Furthermore, the proposed distributed methods effectively address system complexities, providing reliable performance guarantees and scalability for complex VPP operations

Full textA PhD thesis "on the job" is a bridge between the academic and the economic world. In this thesis, these two worlds came together to provide solutions to Swiss companies that want to create virtual power plants (VPP). In order to be able to tackle the subject, I started the thesis by analysing the legislative aspects that have allowed the development of this technology, where the most important element is the "Winter pack" of the European Commission which define common rules to open the energy market. Then I focused on the explanations of the technical developments for the VPP, which are linked to the developments of the "Smart Grid" concept. The end of the introduction of my thesis is a short view on economic theories, which allows the reader to understand the structure of the financial markets where the VPP valuation is possible.After this introduction, which will enable the readers to become familiar with the subject, there are three scientific articles where I have analysed problems that companies are facing in this sector. The forecasting of energy demand, production, and secondary market prices.The articles have helped to address the issues by providing efficient forecasting methodologies in comparison with the literature; in addition, companies use some of these models.The methodologies to answer these issues come from the world of finance (ARMA, SETAR, Var) and machine learning (LSTM, GRU), but also from contributions from other disciplines such as marketing (MCA) and geostatistics (IWD)

Full textAs variable renewable energy plants penetrate significantly the electricity generation mix, they are expected to contribute to the supply of reserve power, albeit the high uncertainty levels on their production. A solution to reduce the uncertainty consists in aggregating renewable plants dispersed over several climates to obtain a smoother production profile and operate them within a Virtual Power Plant control system. In this thesis, a series of probabilistic forecasting models are proposed to assess the capacity of a variable renewable Virtual Power Plant to provide ancillary services with maximum reliability: these models are adapted decision-tree regression models, recurrent and convolutional neural networks, as well as distributions dedicated to extremely low quantiles. The combination of energy sources (Photovoltaics, Wind, Run-of-river Hydro) is considered in detail. Optimal strategies for the joint offer of energy and ancillary services by a variable renewable Virtual Power Plant are later defined, based on production forecasts and market uncertainties. Offer strategies explore several modelling options:dependence between renewable production and prices via a copula, controlled rate of reserve underfullfilment with a chance-constraint optimization, and finally offer of multiple ancillary services thanks to a Lagrangian formulation

Full textRenewable Energy Sources (RES) has grown remarkably in last few decades. Compared to conventional energy sources, renewable generation is more available, sustainable and environment-friendly - for example, there is no greenhouse gases emission during the energy generation. However, while electrical network stability requires production and consumption equality and the electricity market constrains producers to contract future production a priori and respect their furniture commitments or pay substantial penalties, RES are mainly uncontrollable and their behavior is difficult to forecast accurately. De facto, they jeopardize the stability of the physical network and renewable producers competitiveness in the market. The Winpower project aims to design realistic, robust and stable control strategies for offshore networks connecting to the main electricity system renewable sources and controllable storage devices owned by different autonomous actors. Each actor must embed its own local physical device control strategy but a global network management mechanism, jointly decided between connected actors, should be designed as well.We assume a market participation of the actors as an unique entity (the coalition of actors connected by the Winpower network) allowing the coalition to facilitate the network management through resources aggregation, renewable producers to take advantage of controllable sources flexibility to handle market penalties risks, as well as storage devices owners to leverage their resources on the market and/or with the management of renewable imbalances. This work tackles the market participation of the coalition as a Cooperative Virtual Power Plant. For this purpose, we describe a multi-agent architecture trough the definition of intelligent agents managing and operating actors resources and the description of these agents interactions; it allows the alliance of local constraints and objectives and the global network management objective.We formalize the aggregation and planning of resources utilization as a Markov Decision Process (MDP), a formal model suited for sequential decision making in uncertain environments. Its aim is to define the sequence of actions which maximize expected actual incomes of the market participation, while decisions over controllable resources have uncertain outcomes. However, market participation decision is prior to the actual operation when renewable generation still is uncertain. Thus, the Markov Decision Process is intractable as its state in each decision time-slot is not fully observable. To solve such a Partially Observable MDP (POMDP), we decompose it into a classical MDP and an information state (a probability distribution over renewable generation errors). The Information State MDP (IS-MDP) obtained is solved with an adaptation of the Backwards Induction, a classical MDP resolution algorithm.Then, we describe a common simulation framework to compare our proposed methodology to some other strategies, including the state of the art in renewable generation market participation. Simulations results validate the resources aggregation strategy and confirm that cooperation is beneficial to renewable producers and storage devices owners when they participate in electricity market. The proposed architecture is designed to allow the distribution of the decision making between the coalition’s actors, through the implementation of a suitable coordination mechanism. We propose some distribution methodologies, to this end

Full textClimate change mitigation policies in the power generation industry lead commonly on the replacement of bulk generation assets by Renewable Energy Resources (RES-E). Such RES-E are largely distributed among the medium and low voltage grids and most of them are intermittent like photovoltaic and wind power. System Operators expect that such new power system paradigm induces significant complications in their operations. The communities of research and industry started thus to structure themselves in the mid-2000s in order to respond to these coming issues, notably through the deployment of Information and Communication Technology (ICT) in power systems assets, from the Network Operations Centers (NOCs) down to Distributed Energy Resources (DERs) units. This is the Smart Grid. Among the range of possibilities of the Smart Grid, this Ph.D work aims in priority to provide a solution to handle the issue of frequency stability of the power system that are endangered by the combined loss of inertia of the power system and the phasing-out of conventional assets which used to be in charge of the maintain of the frequency in real time through the supply of Frequency Containment Reserve (FCR). The concept developed lead on a process of coordinated modulation of the level of loads of DERs, whose evolve depending on the system frequency measured in real time on-site. The strategy of modulation of each DER follows a pattern which is determined at the scale of the portfolio of aggregation of the DER, depending on the effective level of load of the DER at normal frequency (i.e. 50Hz in Europe). This work is completed by a cost benefit analysis that assesses the opportunity of sharing of the previous infrastructure of coordinated modulation of DERs for the supply of ancillary services and wholesale products. This thesis conducted within Schneider Electric’s Innovation teams and Grenoble Electrical Engineering Laboratory (G2Elab) is linked with the European projects Dream and EvolvDSO, and funded under European Commission’s FP7 program

Full textThe desire to increase the share of renewable energies in the energy mix leads to an increase inshare of volatile and non-controllable energy and makes it difficult to meet the supply-demand balance. A solution to manage anyway theses energies in the current electrical grid is to deploy new energy storage and demand response systems across the country to counter balance under or over production. In order to integrate all these energies systems to the supply and demand balance process, there are gathered together within a virtual flexibility aggregation power plant which is then seen as a virtual power plant. As for any other power plant, it is necessary to compute its production plan. Firstly, we propose in this PhD thesis an architecture and management method for an aggregation power plant composed of any type of energies systems. Then, we propose algorithms to compute the production plan of any types of energy systems satisfying all theirs constraints. Finally, we propose an approach to compute the production plan of the aggregation power plant in order to maximize its financial profit while complying with all the constraints of the grid
