【摘要】 为充分发挥储能系统的快速功率吞吐能力和冷/热负荷的调节作用,促进分布式电源的主动就地消纳,根据可控分布式电源、储能系统、冷/热负荷的多时间尺度互补特性,提出一种源荷储分层协调控制方法。该方法面向冷热电联供型配电网,按"以电定冷热"原则,将调度过程划分为电源层与用户层,并按上下级进行协调优化,从而确定电能实时调度方案以及冷/热能实时调度方案。按照某园区配电网实际情况进行调度仿真及分析,验证源荷储分层协调控制方法的合理性与有效性。调度结果表明,该方法在保证园区重要电负荷供电的同时,最大限度地供应了冷/热能,实现了配电网的协调优化运行以及能源利用方式的精细化、集约化发展。更多还原

【Abstract】 In order to give full play to the fast power handling capacity of the energy storage system and the regulation of the cold/heat load,promotes the active local consumption of distributed generations. A generation-load-storage layered coordinated control method is proposed,according to multi-time scale complementary characteristics of controllable distributed generations,energy storage systems and cold/heat loads. The method is oriented to the CCHP system,the scheduling process is divided into power layer and load layer on the basis of the principle of " allocating cold/heat energy based on electric energy". The two levels are coordinated and optimized according to the upper and lower levels,to determine the real-time dispatching scheme of electric energy and the real-time scheduling scheme of cold/heat energy. Through the actual situation of a distribution network in a park,scheduling simulation and analysis,the rationality and effectiveness of the generation-load-storage layered coordinated control method are verified. The scheduling results show that while ensuring the important electrical load of the park,the cold/heat energy is supplied to the maximum extent,so as to realize the coordinated optimization operation and the refined and intensive development of energy utilization.更多还原
