文摘The highway service area,with facilities for electricity-hydrogen charging,includes multi-energy load energy demands and domestic waste process demands.Based on these needs,a fully renewable energy based multi-energy microgrid with electricity-hydrogen charging services and waste process capacity is proposed.This paper studies the energy input and output characteristics of multi-energy conversion and storage devices,and establishes the model for electricity-hydrogen charging microgrid(EH-CMG).The multi-energy conversion,storage characteristics and multi-energy flow coordination in the EHCMG are then studied.An optimization model and its algorithm solution,based on constraints such as the charging time of vehicles,the reliability of multi-energy load energy supply and the available grid regulation performance in the EH-CMG,are established.The proposed optimization of EH-CMG is illustrated with the actual multi-energy operation data of a highway service area in northwest China.The results demonstrate that the proposed EH-CMG and its optimization method can achieve economic benefits for a multi-energy system with the ability of waste process,electricity-hydrogen charging,and also provide better regulation characteristics for the power grid.
