【摘要】：在光伏上网电价低于市电电价的环境下,光伏用户通过集群的方式实现电能共享,可以获得比单独运行更好的效益。为了使光伏用户群内各经济主体能实现有序的电能交易,提出了一种基于光伏电能供需比(SDR)的内部价格模型。在考虑经济性和舒适度的基础上,提出了用户参与需求响应(DR)的效用成本模型。由于内部电价是以各时段光伏用户群内的供需比为基础,用户之间针对电价的需求响应行为可构成非合作博弈,在证明该博弈问题存在纳什均衡解的基础上,提出了分布式优化算法对用户的纳什均衡策略进行求解。最后,通过实际算例验证了所提模型在减少用电成本、提高光功率互用水平上的有效性。
[Abstract]:In the photovoltaic power tariff is lower than the city electricity price environment, users can share through the photovoltaic cluster to achieve power, can obtain better benefits than the separate operation. In order to make photovoltaic users various economic entities to achieve orderly electricity trading, based on photovoltaic power supply and demand ratio (SDR) of the internal price model. Based on the consideration of economy and comfort, the user participation in demand response (DR) of the utility model. Because of the internal cost price is to supply and demand in each period in the PV user group is based on the ratio between users, for electricity demand response behavior may constitute a non cooperative game, in the game to prove the existence of based on the Nash equilibrium solution of the problem, puts forward a distributed optimization algorithm for users of the Nash equilibrium strategy is adopted. Finally, through a practical example, the validity of the proposed model to reduce electricity costs, improve the optical power Effectiveness on the level of interoperability.
