Abstract

This paper proposes a planning method for cross-regional electricity-gas integrated energy system based on seasonal complementary characteristics. Kendall correlation analysis is used to analyze the seasonal complementary characteristics of electricity-gas integrated energy system in typical regions of China, and a joint planning model for electricity-gas integrated energy system is constructed, which integrates long-term and short-term coordinated energy storage mechanisms and flexible selection of cross-regional energy transmission modes with consideration of different time lag characteristics. Finally, an example of a cross-regional electricity-gas integrated energy system is constructed based on the actual data of Meng-Ji-Lu in China, and the validity of the proposed model is verified, which shows that the energy interconnection through the cross-regional electricity-gas integrated energy system can effectively improve the economy and energy efficiency of the system operation and analyzes the influence of the energy transportation mode on the improvement of the performance of the cross-regional system.
