Dispatching Strategy for New Energy Output Uncertainty

Abstract

Aiming at the shortcomings of traditional microgrid dispatching, this paper takes wind-light-diesel-storage system as the research object, and puts forward a new energy output composite forecasting model. At the same time, aiming at the uncertainty of new energy output such as wind power and photovoltaic in microgrid, a new microgrid system scheduling model is proposed. Then, the (Load Loss Rate, LLR) and confidence probability are used to evaluate the system model scheduling. The results show that the wind-light-diesel-storage system scheduling model considering the uncertainty of new energy output proposed in this paper can reduce the impact of the uncertainty of new energy output on the system, and this method can effectively balance the economy and security of the system.
