计及综合需求响应的电-热综合能源系统分布式光伏最大接入容量评估

为提高综合能源系统分布式光伏的接入容量，考虑电、热多元综合需求响应，建立了电-热综合能源系统对分布式光伏的最大接入容量评估模型。首先，建立电-热综合能源系统的稳态数学模型。然后，基于价格型需求响应、激励型需求响应与弹性热负荷响应，建立了包含电力与热力负荷的综合需求响应的模型。最后，以分布式光伏接入容量最大为目标函数，建立了综合能源系统的接入能力评估模型，并通过松弛技术将问题转化为混合整数二阶锥规划问题。IEEE-33与百利岛33节点耦合系统的算例证明了所提方法的有效性。

Maximum Access Capacity Assessment of Distributed Photovoltaic in Integrated Electric-Thermal Energy System Considering Integrated Demand Response

In order to increase the accessed capacity of distributed photovoltaic in integrated energy system， maximum access capacity assessment model of distributed photovoltaic in electric-thermal integrated energy system （IES） is established considering electric-thermal integrated demand response. Firstly，steady mathematical model of electric-thermal IES is established. Then，the integrated demand response （IDR） involving electrical and thermal load is modeled based on the principle of price， incentive and flexible demand response. Finally， taking the maximum PV hosting capacity as the objective function， the access capacity model for IES is established. The relaxation technique is used to transform the problem into mixed integer second-order cone programming problem. The effectiveness of the proposed evaluation method is proved by the IEEE-33 and Barry island 33-node coupling system.
