6 · A battery energy storage system (BESS), due to its very fast dynamic response, plays an essential role in improving the transient frequency stability of a grid. The performance of the BESS varies with the system''s installation site. Hence, the optimal location of the BESS is of utmost importance for improving transient frequency stability.
The grid frequency drops when more power is taken out of the grid than put into it; likewise, frequency increases when more power is pushed into the grid than taken out. Power plants adjust production ever so slightly to stabilize the frequency within a tight range (around 50 hertz in Europe). But as we see below, the blue line representing ...
