A Regional Integrated Energy Optimization Method Considering Power to Gas

With the extensive development of renewable energy, the instability of renewable energy and the lag of power grid construction lead to the serious phenomenon of abandoned wind and light, resulting in a lot of waste of resources and more serious economic losses. The proposed energy Internet can effectively solve the problem of large-scale renewable energy consumption and improve the utilization of new energy. This paper proposes a regional integrated energy optimization model with the objective of optimizing the economic benefits of the region 24 hours ago. The model introduces the power to gas technology, and considers the wind power and load characteristics of the target region, and converts the surplus wind power after satisfying the regional electric load into the easily stored natural gas, and then sells the natural gas to the regional users. Finally, simulation experiments result verify the potential of wind power absorption and the considerable economic benefits that it can bring us.
