Layered real-time optimization and coordinated control of active distribution network considering distributed generation

Reasonable scheduling method is the key to realize the safety and economic operation of active distribution network. Considering the real-time volatility of new energy generation such as wind or photovoltaic, real-time control is required during the scheduling process. At present, the active distribution network optimization scheduling has less research in terms of covering various loads of cold, heat and electricity. On the basis of considering the real-time volatility of distributed generation, a layered real-time optimization and coordinated scheduling method is proposed. The power layer is responsible for the power supply of important electrical loads, the load layer regulates the output of the gas generator, and the remaining schedulable power is used to meet the cold/heat load demand, thereby realizing the refined and intensive development of the energy utilization mode. Through the simulation and analysis of the actual situation of the active distribution network in a park, the rationality and effectiveness of the layered coordination control method are verified.
