Abstract. This paper examines the development of lead–acid battery energy-storage systems (BESSs) for utility applications in terms of their design, purpose, benefits and performance. For the most part, the information is derived from published reports and presentations at conferences. Many of the systems are familiar within the
Current power systems are still highly reliant on dispatchable fossil fuels to meet variable electrical demand.

A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed. Several battery chemistries are available or under investigation for grid-scale applications, including
RFB is suitable for selection of peak shaving, emergency power supply, and renewable energy storage [104], [105]. Alongside the peak shaving services, the ESS can provide several types of ancillary services which are the prerequisite to maintain the stability and reliability of the grid.
When BESS delivers real energy to the grid, it will be positive and otherwise, it is negative (charging mode).

New coal power units for serving peak-load demand are a destructive option, while DR, pumped storage, life-extended coal units, and even cross-provincial transmission for optimal dispatching are far more economical alternatives for short-term peak power supply. Peak resources should be reasonably rewarded with an
Baseload is a concept that describes a characteristic of the power demand side, and not a necessity of the supply side. In the example in Figure 1, baseload is about half peak load capacity. this illustrates that, for a typical power system, baseload constitutes more than half of total annual electricity demand.

Peaking power plant. Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. [1] Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power.
Fortunately, energy storage (ES) can decrease the peak-valley gap of the net load via charging and discharging process, so it can operate coordinately with coal
