The energy storage configuration should be converted to independent operation mode through technological upgrading. This transformation enables the original abandoned output power from the wind and solar can be stored and thereby increasing revenue through the consumption of otherwise discarded electricity.
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).
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.
The revenue of energy storage in the UK front-of-the-meter market mainly comes from independent energy storage or energy storage jointly participating in the capacity market to obtain frequency regulation benefits, and the contribution of the energy market to energy storage cost alleviation is relatively small.
Compared with the independent configuration of energy storage, the configuration of SES mode reduces the capacity allocation scale by 189.93 kWh and the power allocation scale by 137.93 kW. In Scenario 4, the shared energy storage operator obtains an annual revenue of 256,191 ¥/year, an increase of 7180 ¥/year compared to Scenario 3.
Considering the high investment cost of the energy storage system, it is proposed that the shared energy storage will participate in the operation mode of the multi-virtual power plant system as an independent subject, which will help to realize a win-win situation in cooperation between the VPP operator and the shared energy storage operator.
