Abstract:

Aiming at the problems about wind abandonment and power supply gap caused by transmission limit, an optimal dispatch [JP+1]method of multi-energy grid considering power to gas（P2G） is proposed. Gas turbine is built to solve the power supply gap problem, and P2G equipment is built to solve the wind abandonment problem. Firstly, the reasons for wind abandonment and power supply gap in different regions are analyzed, and then the models of P2G equipment, gas turbine and multi-energy grid dispatch are established. The effectiveness of the proposed dispatch method is verified by a practical example in a certain area. Furthermore, power sensitivity of P2G equipment and gas turbine is analyzed, and the reasons for their sensitivity characteristics is analyzed by the probability distribution of the original wind abandonment and the original power supply gap.
