View DetailsAbstract: 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 during peak-shaving and valley filling is calculated under the constraint conditions of peak-valley difference improvement target value, grid load, battery power, battery capacity, etc.
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.
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.
This study proposed the peak load optimization model to minimize the total cost by combining newly added PV installations, USDR, and ES. The total cost is equal to the sum of the costs of the three measures, ignoring the system consumption costs of the new PV.
ES can precisely match the peak load reduction needs. Thus, deploying ES power stations is the most flexible and effective load peak regulation measure, which reduces the peak load without waste. However, the cost of constructing ES power stations is very high.
