    摘要:

    综合能源系统中储能优化配置和需求侧响应的应用，可解耦热电联产机组(CHP)运行的“以热定电”约束，提高能源利用效率。因此，考虑源荷双侧发电、供热、用电、用热性能，在源侧加电、热储能实现热电联产机组的热电解耦，荷侧充分利用电、热综合需求(IDR)资源可调度资源，建立考虑综合需求响应的区域综合能源系统电、热储能容量优化配置模型。该模型考虑储电储热约束、功率平衡约束等，以区域综合能源系统年总费用最小为目标，解决电、热储能的经济配置最优问题。算例结果表明，电、热储能与负荷侧协调运行可降低运行成本，考虑综合需求响应可减少储能配置容量。源侧储能配置和负荷侧的综合需求响应促进风电消纳，提高综合能源系统运行的经济性、精准性和灵活性。

    Abstract:

    The application of energy storage optimization configuration and demand?side response in the integrated energy system can decouple the constraints of "heating to determine power" in the operation of combined heat and power (CHP) units, and improve energy utilization efficiency. Therefore, taking the performance of power generation, heating, electricity consumption and heat consumption on both sides of the source and charge into account, installing the electricity?heat energy storage equipment on the source side to realize the thermoelectric decoupling of CHP, and fully utilizing the dispatching value of the electricity?heat integrated demand response (IDR) resources on the load side, an optimal configuration model for electric and thermal energy storage capacity of regional integrated energy systems considering the integrated demand responses is established. The model considers the constraints of electricity storage and heat storage, power balance constraints, etc., and aims to minimize the total annual cost of the regional comprehensive energy system to solve the problem of optimal economic allocation of electricity and thermal energy storage. The results of case study show that coordinated operation of multiple energy storage and load side can reduce operating cost, and considering the integrated demand response reduces the configuration capacity of energy storage. The energy storage configuration on the source side and the integrated demand response on the load side promote wind power consumption, and improve the economy, precision and flexibility of the integrated energy system operation.
