Energy Storage Introdution
Along with the delevopment of renewable energy, the consumption of our electricity towards more clean and efficiency,meanwhile, following the increase of renewable energy proportion, there comes out some problems on how to balance the renewable energy and our grid, the key diffcults are:
1. The fluctuation output of renewable energy will cause stability issue in our electricity supply;
2.The renewable energy have a certain time frame, which couldn't cover all of our load requirements.
Energy storage is a technology which can help us solve the problems above. Basically, energy storage is a kind of technology to store energy by certain method and release the stored energy when it's necessary.
For example, we can store the PV genarated electricity by charging to a battery on day time,when the PV genaration has any excess, and release the enery to load on night time by discharging the charged battery , where we don't have any PV genaration.
