含多个能源站的区域综合能源系统建模及协同优化运行策略
|
摘要
区域综合能源系统通过统一调度不同能源设备,协调优化电、气、冷、热多种能源系统来提高区域供能的经济性和环保性。但是多种能源的耦合提高了系统运行的复杂性,因此需要有效的优化方法来保证其运行经济性。通过分析多能源站区域综合能源系统结构,构建了区域综合能源系统模型。在此基础上,提出了一种以系统运行经济性为目标、包含多个能源站的区域综合能源系统协同优化调度方法。案例仿真结果显示,多能源站协同优化运行可以大幅提高区域综合能源系统运行的经济性。
Regional integrated energy system improves the economy and environment of energy supply viacollaborative optimal operation of power, gas, cold and heat energy systems. However, the coupling of multiple energy sources increases the complexity of system operation. Reasonable operation optimization method is the key point to ensure its economy. The structure of the regional integrated energy system that consists of multiple energy stations is analyzed. A practical model of the multi-energy station regional integrated energy system is established. On this basis, a collaborative optimal dispatching method for the regional integrated energy system with multiple energy stations is proposed, which aims at the economic operation of the system. The simulation results of a practical case show that collaborative optimal operation for multiple energy stations can significantly improve the overall economy of the regional integrated energy system.
