Applicability of Energy Storage System (ESS) in Wind and Solar Systems

Renewable energy is mostly environmentally friendly, So, Increasing the usage of it in the power grid is a very important subject today. But some renewable energies highly depend on environment conditions. The output always has fluctuation over time. The energy storage system (ESS) could help renewable energy smooth the fluctuation. There are researches about different ESSs. However, there are research gaps on how could these ESSs be used in renewable energy production and usage. So, this research analyzed different ESS and how could they fit in the wind and solar energy systems. This research collects data about different ESSs, including mechanical, chemical, and electromagnetic ways to store energy. The data contains energy density, power rating, responding time, power rating, suitable storage time, lifetime, capital cost, and so on. Then, we use these data and the features of wind and solar energy to analyze how could these ESSs be used to increase wind and solar power penetration. Some ESSs could be helpful in the wind and solar power systems, but others need some improvement.
