Energy Storage for Power System Planning and Operation offers an authoritative introduction to the rapidly evolving field of energy storage systems.
The operational states of the energy storage system affect the life loss of the energy storage equipment, the overall economic performance of the system, and the long-term smoothing effect of the wind power. Fig. 6 (d) compares the changes of the hybrid energy storage SOC under the three MPC control methods.
With the advancement of new energy storage technol-ogies, e.g. chemical batteries and flywheels, in recent years, they have been applied in power systems and their total installed capacity is increasing very fast. The large-scale development of REG and the application of new ESSs in power system are the two backgrounds of this book.
The precondition for the effectiveness of the control strategy is to ensure that the energy storage is equipped with sufficient capacity to avoid the inability to track the target power. However, a larger energy storage capacity is not always better, considering economic factors.
The energy management, operation control methods, and application scenes of large-scale BESSs were also examined in the study. Energy storage is one of the key means for improving the flexibility, economy and security of power system. It is also important in promoting new energy consumption and the energy Internet.
Losses in energy storage systems (ESSs) result from losses in battery systems and power conversion systems (PCSs). Thus, the power difference between the input and output occurs as a loss, which is considered an operational cost. Additionally, since battery systems consist of modules, there is always a temperature difference.
