Day-ahead Optimization of Integrated Energy System in Highway Service Area with P2G and Composite Energy Storage
In order to improve the absorption capacity of renewable energy and reduce the economic cost of the integrat-ed energy system in the highway service area,based on the energy hub matrix modeling method,we established the coupling characteristic models of energy conversion and supply & demand for each module on the energy supply side,energy conversion side and load demand side for the multi-state energy in the highway service area.Under the condition of fully absorbing renewable energy,we established the optimal scheduling model of system with the minimum total op-erating cost as the objective function.The scheduling results under the same load and different operating scenarios show that the proposed model can maximize the utilization of wind power generation and reduce the total operating cost of the system.The scheduling results of electric coupling on the supply side and complex energy storage on the load side show that the proposed model can achieve the optimal operating cost of the system,and at the same time can realize the"peak cutting and valley filling"of the operating cost within the system cycle.
