【Abstract】 The combination of power to gas(PtG)technology and energy storage equipment can greatly increase the local consumption of renewable energy and reduce system abandonment. For the integrated energy system formed by the coupling of electricity,gas,heat and cold energy in the region,the system is modeled firstly,the working principle of PtG technology and multi-type energy storage devices are introduced in detail. Secondly,the joint optimization model of PtG and multi-type energy storage equipment is established with the goal of the lowest total annual system cost and the model is linearized by Big-M method. Finally,based on the typical daily load and wind power forecasting curve in different seasons,the simulation results show that the joint optimal configuration of the PtG and the multi-type energy storage equipment is beneficial to maximize wind power consumption and improve the overall economy of the system.更多还原
