About Photovoltaic Energy StorageThe peak regulation model posits the minimum peaking cost of each unit as the objective function. It employs the power upper and lower limits, together with the power balance of each unit, as the constraint conditions. Consequently, a peak regulation strategy for the energy storage cluster is devised on a time scale of 1 hour.
About Photovoltaic Energy StorageIn recent years, the impact of renewable energy generation such as wind power which is safe and stable has become increasingly significant.
