Optimal dispatching of integrated energy system considering integrated demand response and multi-energy storage devices

Abstract

As a physical carrier of energy Internet， integrated energy system can improve energy utilization efficiency. Therefore， its optimal dispatching has attracted extensive attention of scholars all over the world. Firstly， the comprehensive demand response and the operation model of multi-energy storage device are modeled； Then， the minimum total operation cost of the integrated energy system is taken as the objective function to construct the optimal dispatching model of the integrated energy system considering the comprehensive demand response and multi-energy storage devices； Then， the CVaR （conditional value at risk） is used to deal with the output uncertainty of renewable energy； Finally， an example of an electric-heat-cold integrated energy system is analyzed. The results show that the model proposed in this paper can reduce the operation cost of the integrated energy system and measure the operational risk caused by output uncertainty of renewable energy.
