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.
