Research on Coordinated and Optimized Operation of Distribution Networks Containing High Permeability Distributed Renewable Energy

With the increasingly serious problems of global warming and environmental pollution, how to save energy and reduce emissions is receiving more and more attention from people around the world. Vigorously developing new energy has become an unstoppable trend. This paper focuses on the coordination and optimal operation of distribution network under the uncertainty environment. Based on the day ahead operation optimization, Model predictive control is adopted, and a multi period coordination and optimal operation strategy of distribution network taking into account the fluctuation of renewable energy output and load forecasting is proposed. The objective of real-time correction of the operation strategy results of the day ahead scheduling is to minimize the deviation of the operation strategy of the day ahead real-time correction. Through example analysis, it is verified that Model predictive control can deal with the errors in the day ahead based on the day ahead scheduling strategy and real-time rolling optimization scheduling.
