Abstract: Integrated energy systems can promote the consumption of renewable energy due to the cascade utilization of energy. The emergence of power to gas (P2G) equipment can greatly promote wind power consumption. Based on the concept of energy center, it has established electrical transmission. The integrated energy system model of power to gas (P2G) equipment is based on the lowest operating cost of the system as the target for scheduling research. In the constraints, the power constraints, energy conversion equipment, and energy storage equipment's operating constraints are considered. Through simulation examples on the MATLAB platform, two different scenarios are constructed, which are considered the wind power capacity of the system with and without P2G equipment. The results show that the addition of electricity to gas (P2G) equipment promotes the system's dissipation of wind power.
Key words: integrated energy system; power to gas; energy hub; economic dispatch
