During the peak shaving process, the energy storage devices are charged while the system load of the grid network is low, which will be discharged to remove only the peaks of the load. During the load leveling process, the same process proceeds to aim to flatten the load instead of removing the system''s peaks [ 12 ].

Battery Energy Storage System (BESS) can be utilized to shave the peak load in power systems and thus defer the need to upgrade the power grid. Based on a rolling load forecasting method, along with the peak load reduction requirements in reality, at the planning level, we propose a BESS capacity planning model for peak and load …
