Multi-objective optimal scheduling of microgrid considering green power share

The tariff regulation mechanism is a key means to guide the benign interaction between microgrid and grids, and an important measure to improve the low-carbon energy transition. This paper proposes a microgrid optimal scheduling method considering the green power ratio to promote the high proportion of new energy operation of microgrid. Combining the green power ratio index of the microgrid with the time-sharing tariff mechanism, and increasing the penalty cost for wind and light abandonment phenomena, the microgrid is encouraged to operate with a high proportion of new energy. The simulation results show that the microgrid's green power ratio index can be used to regulate the tariff to improve the comprehensive utilization rate of new energy and reduce the total carbon emission of the system while taking into account the economy and reliability.
