Dielectric capacitor is a new type of energy storage device emerged in recent years. Compared to the widely used energy storage devices, they offer advantages such as short response time, high safety and resistance to degradation. However, they do have a limitation in terms of energy storage density, which is relatively lower.
While batteries and capacitors are both energy storage devices, they differ in some key aspects. A capacitor utilizes an electric field to store its potential energy, while a battery stores its energy in chemical form. Battery technology offers higher energy densities, allowing them to store more energy per unit weight than capacitors.

However, the problem arises because RES especially solar and wind energy are intermittency, highly dependent on nature, and leading to unstable load power supply risk. Using a battery energy storage system (BESS) is one way to overcome instability in the power supply and increase flexibility and RES penetration in Indonesia.
