Optimal electric energy storage for the future

Why is energy storage important in electrical power engineering?

Various application domains are considered. Energy storage is one of the hot points of research in electrical power engineering as it is essential in power systems. It can improve power system stability, shorten energy generation environmental influence, enhance system efficiency, and also raise renewable energy source penetrations.

How to optimize the energy storage system?

The uncertainty of photovoltaic power generation output, electric vehicle charging load, and electricity price are considered to construct the IRL model for the optimal operation of the energy storage system. A double-delay deep deterministic policy gradient algorithm are utilized to solve the system optimization operation problems.

What is the optimal operation problem of energy storage?

Conclusions In this paper, the optimal operation problem of energy storage considering energy storage operation efficiency and capacity attenuation is established, and the double-delay deep deterministic policy gradient algorithm is used to solve optimization operation results.
