Abstract

Abstract: In order to optimize the economic operation of integrated electricity-gas system (IEGS) and take into account the effective cooperation of multi-energy storage (MES) equipment and integrated demand response (IDR), an optimal dispatching model suitable for regional IEGS is proposed in this paper. In the optimal dispatching model, combined with the demand response characteristics of different energy loads, according to the prices of electric power and natural gas, the IDR of terminal users is described in detail from the aspects of curtailable load, shiftable load and transformable load, so that they can effectively cooperate with the operation of MES equipment in IEGS to minimize the operating costs of the system. The validity of the proposed model is verified by relevant examples. The simulation results show that the regional IEGS operators can fully utilize the space-time complementary characteristics of electric power and natural gas loads through the comprehensive application of MES and IDR, maximize the wind power accommodation capacity of the system, and further decrease the operation costs of the system.

Key words: integrated electricity-gas system（IEGS）, multi-energy storage（MES）, ntegrated demand response（IDR）, optimal dispatching, wind power accommodation capacity
