Flexible load dispatching strategy for substation considering time-of-use price

Abstract

Abstract The substation is an important node in the power system. Reducing the operating costs and carbon emissions of substations is of great significance for power enterprises to reduce costs and carbon emissions. Meanwhile, with the development of new substations, more substations have added rooftop photovoltaic systems to reduce carbon emissions. How to improve the utilization rate of rooftop photovoltaic power generation has also become a key focus of substation development. This article establishes a flexible load optimization scheduling model for substations, and based on the consideration of system costs, sets up two scenarios for comparison. The research results indicate that the flexible load optimization scheduling model for substations can significantly reduce the operational carbon emissions and costs caused by electricity consumption within the substation.
