Research on Coordinated Optimal Control Strategy of Residents and Power Grid

Improving the utilization ratio of the system and resources plays a very important role in the power industry and environmental protection. This paper introduces the output characteristics of photovoltaics and fans on the supply side of residents, and the load characteristics of air conditioning and electric vehicles on the demand side. According to the time-of-use tariff division of typical daily load of residents, a set of optimal control strategy is proposed, that is, during peak load, residents adjust load and generate electricity with micro-grid. The example shows that this strategy can reduce the peak load, fill the load trough, reduce the peak-valley difference of power grid load, which plays a positive role in peak cutting and valley filling.
