考虑广义储能的综合能源系统典型日优化运行

由电、热、冷能系统之间的耦合与互联构成的综合能源系统(IES),对于构建环保、高效、经济的能源系统至关重要。着眼于IES运行环节,考虑广义储能设备的投入运行,并计及IES内各设备出力约束,以调度周期内运行费用最低为目标函数,采用基于yalmip平台的cplex优化算法包对IES优化运行进行求解。该方法考虑了分时电价和典型日负荷特性对IES运行的影响,并与不计广义储能的运行模式进行对比分析。算例仿真表明,投入广义储能设备不仅更有利于IES的经济效益,而且有利于IES安全稳定运行。

Optimal Operation of Typical Daily Integrated Energy System Considering Generalized Energy Storage

The integrated energy system based on the coupling and interconnection among electric, thermal and cold energy systems is very important for building an environment-friendly, efficient and economical energy system. Focusing on the link of the operation of integrated energy systems, considering the input generalized energy storage equipment operation and the equipment output constraints of the integrated energy system, the lowest operating cost in the scheduling period is taken as the objective function. The cplex optimization package based Yalmip platform is used to solve the integrated energy system optimization problem. This method effectively considers the impact of price and the typical daily load characteristics on the integrated energy system operation, and compares with the operation mode of no energy storage system. The simulation results show that the generalized input energy storage equipment is not only more conducive to the integrated energy system''s economic benefits, but also conducive to the safe and stable operation of the integrated energy system.
