多区域含冷热电联供和储能的综合能源系统运行优化
Operation optimization of multi-region integrated energy system including cool-heat-electricity cogeneration and energy storage equipment
综合能源系统(Integrated Energy System，IES)是增加可再生能源消纳能力、提高能源利用效率、实现可持续发展的关键技术，多区域IES运行优化将各个区域根据负荷特性进行协同优化是重要研究方向。建立了含冷热电联共及储能的多区域IES优化混合整数线性优化模型，区域间通过热网交互，并采用场景分析法模拟可再生能源波动性，使用Yalmip和Cplex在MATLAB中进行优化分析。结果表明：考虑风电不确定性的多区域IES优化运行能实现热能的协调分配，提高系统能源利用率，储能设备可解耦热电联系改善系统运行经济性。
英文摘要:
Integrated energy system (IES) is a key technology to increase renewable energy absorption capacity, improve social energy utilization efficiency and achieve sustainable development. It is an important research direction for multi-region IES operation optimization to carry out collaborative optimization of each region according to load characteristics. In this paper, the mixed integer linear optimization model of multi-region IES optimization including cool-heat-electricity cogeneration and energy storage equipment is established, areas interact through the heat network and the volatility of renewable energy is simulated by scenario analysis method. The Yalmip toolbox and Cplex commercial software are used for optimization calculation in MATLAB. The results show that the multi-region optimal operation considering the uncertainty of wind power can realize the coordinated distribution of thermal energy, improve the energy utilization of the system, and the energy storage equipment can decouple the thermoelectric connection to improve the operation economy of system.
