A Novel Integrated Energy System Decision Model Based on Minimax Regret Criterion

With the development of integrated energy system, amount of electrical equipment are synchronized to the power grid, making the operating conditions of distribution network rather complicated, so as to the requirement of power system operation and management being improving. However, the refined management of electrical energy has always been a difficult problem, because electricity are not able to be stored on a large scale, not to mention some renewable energy cannot be predicted accurately. In order to reduce the stochastic effect of new energy generation, such as photovoltaic, this paper introduces the concept of minimax regret criterion to model an integrated energy grid energy management system to improve the efficiency and economic benefit. Meanwhile, both operating conditions and maintenance requirements are taking into consideration so as to make the total energy cost minimum and the local distributed power utilization maximum. The time- domain rolling method is applied to solve this model. At last, a study case is used to verify the proposed method.
