摘要
气电联合系统协同运行能显著提高能源利用效率，其运行优化得到了广泛关注。文章建立了考虑需求响应（demand response，DR）的气电联合系统经济调度模型，并提出了基于近似动态规划（approximate dynamic programming， ADP）算法的联合系统经济调度策略。首先，采用粒子群（particle swarm optimization ，PSO）优化算法对用户侧的负荷曲线进行优化，从而最小化用户补偿费用和峰谷差率；随后建立线性化的气电联合系统运行模型，借助ADP算法求解。以Grave 6节点电力系统和14节点天然气网络进行仿真分析。仿真结果验证了所提模型和求解算法的有效性，考虑供需两侧的气电联合优化能提高能源利用效率。
Abstract
The operation of integrated gas and power system （IGPS） can significantly improve the efficiency of energy usage， and its operation optimization has received extensive attention. In this paper， an optimal energy flow optimization model of IGPS considering demand response （DR） is established， and the ADP algorithm based economic dispatch policy is proposed for the integrated systems. Firstly， the particle swarm optimization （PSO） algorithm based load curve optimization policy which aims at minimizing the DR compensation cost and peak-to-valley difference rate of load is proposed. Secondly， the IGPS operation model is simplified as a linearized optimization model and approximate dynamic programming （ADP） is adopted. Simulation analysis is performed using a Grave 6-node power system and a 14-node natural gas network. The simulation results verify the validity of the proposed model and the solution algorithm， and show that considering both sides of supply and demand of IGPS can improve the energy efficiency of the integrated energy system.
