含相变储能热泵的综合能源系统优化调度

利用相变储能装置的储能特性，针对热量传输过程中的热延迟与热衰减，建立了考虑热惯性特征的含相变储能热泵的综合能源系统优化调度模型，并采用预测平均评价PMV指标来量化热负荷弹性。运用Dymola与Matlab联合建模，以经济运行总成本为目标函数，对比分析三种不同场景下综合能源系统的削峰填谷能力、可再生能源消纳能力、环境效益与安全性，对冬季典型日进行24小时运行策略优化。算例分析结果表明，考虑热惯性与热负荷弹性的含相变储能热泵的综合能源系统具有更好的经济性与抗故障能力，相较于含常规储热水箱的综合能源系统经济运行总成本降低了6.6％，抗供热故障时间延长3.51h。

Optimal Scheduling of Integrated Energy System with Phase Change Energy Storage Heat Pump

Based on the energy storage characteristics of phase change energy storage device, the optimal scheduling model of the integrated energy system with phase change energy storage heat pump considering the thermal inertia characteristics was established in view of the thermal delay and thermal attenuation in the heat transfer process, the PMV index was used to quantify the thermal load elasticity. Using Dymola and MATLAB to establish the model, taking the total cost of economic operation as the objective function, the capacity of peak-shaving and valley-filling, the capacity of renewable energy consumption, the environmental benefit and the safety in three different scenarios was compared and analyzed, and the 24-hour operation strategy on typical days in winter was optimized. The results show that the integrated energy system with phase change energy storage heat pump considering thermal inertia and thermal load elasticity has better economy and fault resistance.
