Low carbon and economic dispatching of electric-gas integrated energy system with liquid storage carbon capture equipment

Because of the coupling CO 2 absorption and treatment, conventional carbon capture power plants lack flexibility plant operation. This paper provides a liquid storage (LSCCPP) with solution storage, analyzes “energy time-shift” features creates joint operating model LSCCPP Power to Gas(P2G) based on this. Taking into account market trading mechanism, this develops low-carbon economic dispatch for an integrated electric-gas energy system LSCCPP, goal achieving lowest overall cost. Moreover, proposed is solved by transforming mixed-integer linear programing problem calling CPLEX. Finally, modified example used demonstrate validity model. The results show that suggested has significant reference enhancing system’s use wind accomplishing efficient functioning system.
