Battery energy storage is widely used in power generation, transmission, distribution and utilization of power system . In recent years, the use of large-scale energy storage power supply to participate in power grid frequency regulation has been widely concerned.
The application of energy storage in power grid frequency regulation services is close to commercial operation . In recent years, electrochemical energy storage has developed quickly and its scale has grown rapidly , . Battery energy storage is widely used in power generation, transmission, distribution and utilization of power system .
In recent years, the use of large-scale energy storage power supply to participate in power grid frequency regulation has been widely concerned. The charge and discharge cycle of frequency regulation is in the order of seconds to minutes.
New energy is intermittent and random , and at present, the vast majority of intermittent power supplies do not show inertia to the power grid, which will increase the pressure of power grid frequency regulation after large-scale access.
For the energy management strategy of BESS, on the one hand, it is necessary to accurately estimate the SOC of the battery pack in real time , , , , on the other hand, it is necessary to balance the energy of the battery pack to avoid the extreme conditions of overcharge and discharge.
Due to the “short board effect”, the available capacity of BESS will decrease, resulting in failure . Therefore, with the emergence of the scale effect of battery energy storage, the safety problem has become a new risk challenge faced by the development of energy storage. We should pay attention to the safety risk management in time.
