According to [17], if the PV power is limited to 30%, only 2/3 of the generated energy can be injected into the grid or used by the consumer for the cases without ESS. The same study stated that determining ESS size according to the energy consumption is more accurate than the PV power. If ESS is sized properly, SCR can be increased by 10–24%

The energy trading process between the microgrid group and shared energy storage station is as follows: each microgrid in the group can purchase and sell electricity to the shared energy storage station. When the generated power in a microgrid is greater than its load, excess power can be transferred to the shared energy storage station, which

1. Introduction Battery energy storage systems (BESSs) have been deployed to meet the challenges from the variability and intermittency of the power generation from renewable energy sources (RESs) [ 1 – 4 ].
As a result, shared energy storage increased self-consumption rates up to 11% within the prosumer community. The proposed method provides significant economic benefits and improved power quality. Additionally, prosumers need an ESS to improve self-consumption, especially as renewable penetration levels increase in the power grid.
Classified by the form of energy stored in the system, major EES technologies include mechanical energy storage, electrochemical/electrical storage, and the storage based on alternative low-carbon fuels.
According to the DOE OE Global Energy Storage Database, since 2010, more than 50% of energy storage projects are LIB projects . By contrast, although PHES accounts for 93% of the global storage capacity , many of PHES, particularly plants in Europe and US, were built before 1990 .
