The evaluation of energy storage systems is a complex task that requires the consideration of various indicators and factors. Research in this field has focused on the electricity market and incentive policies, aiming to evaluate the economic benefits of energy storage.
Energy storage equipment can realize the input and output regulation of electric energy at different time scales, which can effectively improve the operating characteristics of the system and meet the power and energy balance requirements of a smart grid. The application of different energy storage technologies in power systems is also different.
Techno-economic assessments (TEAs) of energy storage technologies evaluate their performance in terms of capital cost, life cycle cost, and levelized cost of energy in order to determine how to develop and deploy them in the power network.
In , considering the health state of energy storage batteries, a configuration model was established to maximize the net return of the system, and the appropriate ratio of photovoltaic, energy storage, and load was obtained. Energy storage systems are installed in power grids, and the benefits generated have many aspects.
In the optimal configuration model of energy storage, the technical indicators mainly include voltage quality and system network loss.
When uncontrollable renewable energy units are connected to the system, the power-dispatching process becomes more complicated . These problems can be solved with the application of energy storage technology, which can effectively cope with access to new energy with high penetration rates.
