摘要
随着分布式电源普及率越来越高,提高风电、光伏等分布式电源的电能利用率极为重要,现有研究大多通过单一微网内部的优化调度,提高风光消纳率,但单一微网调节程度有限。对此,基于博弈论的思想,对含有多个微网的电力系统进行调度优化,即先在微网内部进行电能的初步调节,然后进行微网的等效优化,再将等效后的微网进行非合作博弈。通过两次调度,充分利用微网间的互补优势,达到经济效益的最大化。最后,通过建立多微网模型,利用实例证明了所提优化调度方案可有效提高多微网系统的风光消纳率。
The popularity of distributed power supplies is getting higher and higher.Improvement of power utilization of distributed power sources such as wind power and photovoltaic generation has become a research hotspot.The scheduling method of distributed power and load inside the microgrid is applied to improve the accommodating rate of wind power and photovoltaic generation.However,the regulation degree of a single microgrid is limited.In this paper,the game theory was used to optimize scheduling of power systems with multiple microgrids.The initial adjustment of electrical energy is first performed within the microgrid.And the equivalent optimization of the microgrid is performed.Then equivalent microgrid is subjected to a non-cooperative game.Making full use of the complementary advantages between microgrids in two scheduling,the economic benefits are maximized.Finally,a multi-microgrid model is established to prove that the scheduling method can effectively improve the accommodating rate of wind power and photovoltaic generation.
