Requirements for energy storage system to reduce peak load and fill valley

Minimizing the load peak-to-valley difference after energy storage peak shaving and valley-filling is an objective of the NLMOP model, and it meets the stability requirements of the power system. The model can overcome the shortcomings of the existing research that focuses on the economic goals of configuration and hourly scheduling.

Abstract: In order to make the energy storage system achieve the expected peak-shaving and valley-filling effect, an energy-storage peak-shaving scheduling strategy considering the improvement goal of peak-valley difference is proposed. First, according to the load curve in the dispatch day, the baseline of peak-shaving and valley-filling .

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.

In this paper, a Multi-Agent System (MAS) framework is employed to investigate the peak shaving and valley filling potential of EMS in a HRB which is equipped with PV storage system. The effects of EMS on shiftable loads and PV storage resources are analyzed.

With the advancement of market-oriented reforms, the role of demand response on peak shifting and valley filling has become increasingly prominent. As for energy storage system, it can charge when the load is low, and plays the role of power consumer; discharge at the peak load and acts as a power supplier.
