Abstract: From the power supply demand of the rural power grid nowadays, considering the current trend of large-scale application of clean energy, the peak shaving strategy of the battery energy storage system (BESS) under the photovoltaic and wind power generation scenarios is explored in this paper.
The decreasing proportion of the peak-valley difference between the power grid and users’ electricity purchasing costs are both lower than that in the base case when the load reduces by 20%. Thus, the dynamic price mechanism proposed in this study exhibits more obvious effects on peak shaving and valley filling when the power grid is overloaded.
(2) A dynamic price incentive mechanism for peak shaving and valley filling is proposed in this study. The dynamic price mechanism can thoroughly explore the potential of the flexible load in participating in peak shaving and valley filling compared with the conventional fixed price mechanism.
The function of load peak shaving and valley filling is achieved, thus ensuring the safe and orderly operation of the rural power grid. The feasibility of the strategy is verified through simulation results on multiple scenarios, for the decreased PVD of 44.03%, 24.3%, and 33.4% in Scenario 1-3.
In this study, a power grid-flexible load bi-level operation model based on dynamic price is constructed to enhance the activity of the demand side, reduce the peak-valley difference, and enhance the security of the power grid.
