The size of your Energy Storage System(ESS) is one of the most important factors in determining the price and installation for your Energy System. Knowing what size (ESS) you will need will be directly impacted by how much energy you currently use or anticipate using.
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 shaving problem.
