In northern China, thermal power units (TPUs) are important in improving the penetration level of renewable energy. such areas, potentials coordinated dispatch energy sources (RESs) and TPUs can be better realized, if RESs connected to grid at same point common coupling (PCC) dispatched as a coupled system. Firstly, definition system is introduced, followed by an analysis on its characteristics...

This paper presents a new genetic approach based on arithmetic crossover for solving the economic dispatch and environmentally constrained economic dispatch problems. Elitism, arithmetic crossover and mutation are used in the genetic algorithm to generate successive sets of possible operating policies. The proposed technique improves the quality of the solution. The employed arithmetic crossove...

This paper presents a two-stage adaptive robust optimization framework for day-ahead energy and intra-day flexibility self-scheduling of technical virtual power plant (TVPP). The TVPP exploits diverse distributed resources’ (DERs) capabilities in order to offer services wholesale market as well preserving the distribution network's operational constraints presence DER uncertainties. aims at max...

Multi-interval settlement is conducive to meeting the needs of growing renewable energy resources with great intermittency and volatility managing effective operation in electricity spot market. However, insufficient incentive market price inaccurately reflecting total cost caused by inaccuracy generation load prediction current multi-interval will lead inefficient scheduling, causing participa...

Optimal system operation, in general, involves the consideration of economy of operation, system security, emissions at fossil-fuel plants, optimal release of water at hydro power plants etc. and aim at improving the efficiency of the power system. In this research work, consideration will be given to two aspects of the optimal system operation, emissions and economy of operation, also known as...

reliability investigation has always been one of the most important issues in power systems planning. the outages rate in power system reflects the fact that more attentions should be paid on reliability indices to supply consumers with uninterrupted power. using reliability indices in economic dispatch problem may lead to the system load demand with high reliability and low probability of powe...

Solar energy and bioenergy are two leading renewable forms of in the move toward a near-zero-emission electric power industry. Concentrated solar units coupled with thermal storage biomass plant offer dispatchable electricity, raising their ever-growing role future renewable-dominated networks. This paper proposes day-ahead intraday dispatch model for maximizing profit an Integrated Biomass-Con...

Economic dispatch is carried out at the energy control center to find out the optimal output of thermal generating units such that power balance criterion is met, unit operating limits are satisfied and the fuel cost is minimized. With growing environmental awareness and strict government regulations throughout the world, it has become essential to optimize not only the total fuel cost but also...

in today’s restructured environment, congestion management plays an essential role in power system operation. different methods are presented and discussed in this respect for congestion management in short-term and long-term intervals. it is attempted in the present paper to investigate the impact mechanism of facts devices and demand response programs together with generation re-dispatch as s...
