Demand response (DR) is one of the most effective and economical methods for power operators to improve network reliability in face uncertainty emergencies. In this paper, considering wind output failure system components, a two-stage security-constrained unit commitment (SCUC) model established by optimizing real-time pricing mechanism indirectly adjust DR. Firstly, modeled based on self-organ...

This paper presents a comprehensive framework model of a distribution company with security and reliability considerations. A probabilistic wind farm, which is a renewable energy resource, is modeled in this work. The requirement energy of distribution company can be either provided by distribution company’s own distributed generations or purchased from power market. Two reliability indices as ...

Although many countries prefer deregulated power markets as a means of containing costs, monopoly may still exist. In this study, an agent-based bidding simulation framework is proposed to detect whether there will be in the market. A security-constrained unit commitment (SCUC) conducted clear Using characteristics that agent can fully explore certain environment and Q-learning algorithm, each ...

This paper solves reliability constrained unit commitment problem (UCP) for a composite power system network using network equivalent technique. Here, the integration of generation and transmission system reliability forms a composite power system model. The inclusion of load forecast uncertainty for the solution of unit commitment problem will give more accurate assessment of spinning reserve ...

Renewable energy sources (RES) such as wind turbines (WT) and solar cells have attracted the attention of power system operators users alike, thanks to their lack environmental pollution, independence fossil fuels, meager marginal costs. With introduction RES, challenges faced unit commitment (UC) problem a traditional optimization aiming minimize total costs by optimally determining units’ inp...

Unit commitment (UC) is to determine the optimal unit status and generation level during each time interval of the scheduled period. The purpose of UC is to minimize the total generation cost while satisfying system demand, reserve requirements, and unit constraints. Among the UC constraints, an adequate provision of reserve is important to ensure the security of power system and the fast-respo...

Recently, the provision of reserve from energy storage systems (ESSs) is introduced as a source for ancillary services to address uncertainties renewable power generations. The performance ESSs analysed while they are applied provider regulation reserves. It has been revealed that previous stochastic models neglect impact corrective dispatches, related reserves, on level stored in ESSs, which c...
