Book excerpt: Les réseaux électriques sont sujets aux aléas divers pouvant éventuellement mettre en péril leur sûreté. Des évènements résultants de l'aléa météorologique ou de la défaillance stochastique des composants du réseau tels qu'une fluctuation de températures hors saison ou la perte d'une unité de production, peuvent causer des déséquilibres inattendus entre l'offre et la demande et entraîner des délestages. Pour faire face à ces aléas, des marges de puissance ou "réserve" sont ménagées par rapport au strict équilibrage de l'offre et de la demande prévisionnelle. Cependant, déterminer la quantité de réserve suffisante pour une opération fiable et rentable est un problème difficile à résoudre, particulièrement en présence d'incertitude croissante due à la libéralisation du marché de l'électricité et à la pénétration à grande échelle des éoliennes sur le réseau. L'approche déterministe considère un niveau de réserve statique du jour pour le lendemain. L'énergie éolienne étant faiblement prévisible, de la réserve supplémentaire est requise pour pallier l'intermittence du vent. Parce que les éoliennes ne sont pas distribuables, les générateurs conventionnels ont été laissés sous pression en répondant aux variations larges et rapides de la charge nette du réseau. Étant données les contraintes de rampe qui limitent leur flexibilité, le bon fonctionnement du marché de l'électricité peut être altéré parce que les transactions d'énergie qui y sont contractées risquent de ne pas être réalisées en temps réel comme convenu pour des raisons de sécurité. Dans ce contexte, l'utilisation de l'approche déterministe à elle seule comme c'est le cas aujourd'hui, pourrait ne pas être économique ou fiable pour contenir les risques encourus; d'où la nécessité des méthodes sophistiquées basées sur une représentation plus complexe de l'incertitude. Cette thèse propose des solutions viables et efficientes à l'incertitude croissante dans l'opération à court terme des réseaux électriques en présence d'éoliennes à grande échelle et dans un contexte de compétition. Le caractère conservatif de la méthode déterministe a été grandement amélioré par une génération de réserve supplémentaire, contrôlable, et qui tient en compte l'aspect stochastique des éoliennes. La mutualisation des capacités via l'interconnexion permet d'alléger la contrainte d'équilibrage du réseau et de réduire les secousses autour des générateurs conventionnels. Afin de faciliter les transactions d'énergie sur le marché, des règles ont été élaborées pour inciter la mise en disponibilité des générateurs à larges paliers de rampes. Un problème combiné de la programmation des centrales et de transit optimal de puissance incorporant tous les objectifs sus-cités a été formulé. Traduit en programmation mixte quadratique car générant des solutions faisables dont le niveau d'optimalité est connu, celui-ci a été utilisé pour investiguer divers effets de l'interconnexion sur la réduction des coûts d'exploitations associés à plus d'éoliennes sur le réseau. Enfin et surtout, la capacité de notre modèle à résister aux contingences a été validée avec un modèle qui tient compte de l'aspect aléatoire des composants du réseau à tomber en panne. Ce qui nous a permis d'ajuster notre stratégie du marché du jour pour le lendemain par rapport à celui du temps réel. Notre modèle se distingue par sa rapidité et sa capacité `a révéler les coûts cachés de l'intégration des éoliennes dans les réseaux électriques.
Download or read book Improving Deterministic Reserve Requirements for Security Constrained Unit Commitment and Scheduling Problems in Power Systems written by Fengyu Wang and published by . This book was released on 2015 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional deterministic reserve requirements rely on ad-hoc, rule of thumb methods to determine adequate reserve in order to ensure a reliable unit commitment. Since congestion and uncertainties exist in the system, both the quantity and the location of reserves are essential to ensure system reliability and market efficiency. The modeling of operating reserves in the existing deterministic reserve requirements acquire the operating reserves on a zonal basis and do not fully capture the impact of congestion. The purpose of a reserve zone is to ensure that operating reserves are spread across the network. Operating reserves are shared inside each reserve zone, but intra-zonal congestion may block the deliverability of operating reserves within a zone. Thus, improving reserve policies such as reserve zones may improve the location and deliverability of reserve. As more non-dispatchable renewable resources are integrated into the grid, it will become increasingly difficult to predict the transfer capabilities and the network congestion. At the same time, renewable resources require operators to acquire more operating reserves. With existing deterministic reserve requirements unable to ensure optimal reserve locations, the importance of reserve location and reserve deliverability will increase. While stochastic programming can be used to determine reserve by explicitly modelling uncertainties, there are still scalability as well as pricing issues. Therefore, new methods to improve existing deterministic reserve requirements are desired. One key barrier of improving existing deterministic reserve requirements is its potential market impacts. A metric, quality of service, is proposed in this thesis to evaluate the price signal and market impacts of proposed hourly reserve zones. Three main goals of this thesis are: 1) to develop a theoretical and mathematical model to better locate reserve while maintaining the deterministic unit commitment and economic dispatch structure, especially with the consideration of renewables, 2) to develop a market settlement scheme of proposed dynamic reserve policies such that the market efficiency is improved, 3) to evaluate the market impacts and price signal of the proposed dynamic reserve policies.

This book was released on 2021-04-12 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the interaction between different energy vectors, that is, between electrical, thermal, gas, and transportation systems, with the purpose of optimizing the planning and operation of future energy systems. More and more renewable energy is integrated into the electrical system, and to optimize its usage and ensure that its full production can be hosted and utilized, the power system has to be controlled in a more flexible manner. In order not to overload the electrical distribution grids, the new large loads have to be controlled using demand response, perchance through a hierarchical control set-up where some controls are dependent on price signals from the spot and balancing markets. In addition, by performing local real-time control and coordination based on local voltage or system frequency measurements, the grid hosting limits are not violated.
