Typically, based on differences in regulatory policies and electricity price mechanisms at different times, the operation models of energy storage stations can be categorized into three types: grid integration, leasing, and independent operation.
With the expansion of the energy storage market and the evolution of application scenarios, energy storage is no longer limited to a single operating mode. Depending on the location of integration, many countries have gradually developed two main market operating models for energy storage: front-of-the-meter (FTM) and behind-the-meter (BTM).
As the proportion of renewable energy infiltrating the power grid increases, suppressing its randomness and volatility, reducing its impact on the safe operation of the power grid, and improving the level of new energy consumption are increasingly important. For these purposes, energy storage stations (ESS) are receiving increasing attention.
In terms of the operational characteristics of pumped storage, it can use high water levels for power generation and peak shaving of the grid, or it can use low valley power or wind and photoelectric abandoned energy for pumping, converting electrical energy into water potential energy and storing it for backup .
During the three time periods of 03:00–08:00, 15:00–17:00, and 21:00–24:00, the loads are supplied by the renewable energy, and the excess renewable energy is stored in the FESPS or/and transferred to the other buses. Table 1. Energy storage power station.
Energy storage power stations are capital-intensive systems, with high construction costs and long payback periods. Large-scale, long-term energy storage projects are not attractive to most social enterprises and investors.
