Stochastic Optimal Dispatching of Electrothermal Integrated Energy System Considering Uncertainty of Heat Load

Abstract

This paper is based on Cornish-Fisher series to predict solar irradiance in multiple scenarios, and establishes a day-ahead stochastic dispatch model of regional electric heating integrated energy system considering the uncertainty of thermal load. It is verified by simulation that the proposed method has higher accuracy in predicting heat load, can promote the consumption of renewable energy, and effectively reduce the energy cost of users.
