Research on Environmental and Economic Dispatch for Isolated Microgrid System Taken Risk Reserve Constraints Into Account
摘要
Abstract
To solve the troubles in microgrid dispatching caused by the randomness of wind power generation and PV generation, through utilizing the probability distribution function of renewable energy sources to describe the uncertainty factors existing in microgrid and leading in the risk indicator of load loss and the risk indicator of wind power curtailment and wasted solar energy a multi-objective model, in which the generation economy and environmental protection are considered, is established to ensure the reliability of microgrid power supply and efficient utilization of renewable energy sources. The improved multi-objective particle swarm optimization (MOPSO) algorithm is used to solve the proposed model, and then through the entropy weight based decision-making the final dispatching scheme is determined, thus the impact of subjective factor in artificially determining multi-objective weights can be avoided to make the overall benefits of microgrid dispatching optimal. Validity of the proposed model and algorithm is verified by calculation results.关键词
