Real time coordinated optimization dispatch model for AC/DC hybrid distribution network

With the gradual increase of the penetration rate of new energy, the cyber physical system paves a new way for real time dispatch, rational planning and effective utilization of new energy. This paper establishes a dynamic multi-agent real-time coordinated control model for the framework of a typical AC/DC hybrid distribution network and proposes the distributed algorithm. The algorithm includes two parts: optimized dispatch and coordinated control. Firstly, by dispatching and optimizing primary energy, large-scale use and sharing of distributed renewable energy can be realized, energy supply cost can be reduced, and the reliability of energy supply can be improved. Energy Internet provides powerful support for power systems, heating systems, and other major energy networks. Then a coordinated control model based on a dynamic multi-agent system is established to eliminate load fluctuation quickly and efficiently, maintaining the stability of the energy internet. Finally, multi-agent containment control algorithm was applied in the voltage control to guarantee high power quality. According to the actual operation situation of physical devices, the adjustment term serves as a feedback to do real-time correction, in order to make the results satisfy all constraints. Simulation results were presented to demonstrate the effectiveness and robustness of the proposed algorithm.
