Enterprise energy storage power station payback period

Invested by distributed power users, the energy storage power station (ESPS) installed in the power distribution network can solve the operation bottlenecks of the power grid, such as power quality's fluctuation and overload in local areas.

To achieve this, an optimization model is constructed with the objective of minimizing average electricity costs under the prevailing time-of-use pricing policy. The comprehensive evaluation metrics is built using specific CO 2 emissions, average electricity cost, dynamic capital payback period, and energy self-sufficiency rate.

As the share of renewable energy in the energy system increases, the peak-to-valley electricity price gap may widen due to the declining in the cost of renewable energy generation costs or narrow, or may narrow due to the increasing in grid dispatch costs .

And the dynamic capital payback period is 7.214 years; (2) When users operate with optimal economics as the goal, the BESS operation strategy depends on both PV output and the electricity price period division policy.

Sun et al. analyzes the benefits for photovoltaic-energy storage-charging station (PV-ES-CS), showing that locations with high nighttime electricity loads and daytime consumption matching PV generation, such as hospitals, maximize benefits, while residential areas have the lowest.

Among the energy storage technologies, the growing appeal of battery energy storage systems (BESS) is driven by their cost-effectiveness, performance, and installation flexibility [, , ].
