提出分时电价机制下分布式风光接入主动配电网就地消纳模型,该模型通过赋予主动配电网制定网内分时电价的权利来提高分布式风光消纳率。首先分析了基于负荷分类的分时电价机制下负荷的价格型需求响应模型,其次建立了分时电价机制下分布式风光接入主动配电网就地消纳模型,该模型以风光消纳率最大为目标函数,计及多种必要约束。提出采用基于模拟退火算法的求解模型对所建立模型进行求解。最后通过一个算例验证了该文方法可以有效提高分布式风光接入主动配电网的就地消纳率。

This paper proposes a local accommodation model of distributed wind/photovoltaic power accessed to active distribution network based on time-of-use（TOU） power price mechanism,which is able to increase the accommodation rate of distributed wind/photovoltaic power by giving active distribution network the right to set the TOU power price.Firstly,this paper analyzes the price-based demand response of load under TOU power price mechanism based on load classification.Then,this paper constructs a local accommodation model of distributed wind/photovoltaic power accessed to active distribution network based on TOU power price mechanism,whose objective function is the maximum wind/photovoltaic power accommodation rate while considering several necessary constraints.And this paper adopts simulated annealing algorithm to solve the proposed model.Lastly,the example results show that the proposed method can increase the accommodation rate of wind/photo voltaic power accessed to active distribution network effectively.
