The main objective of control strategies is active power control, and reactive power control is a supplementary control. Therefore the coordinate ability of the ESS can be made full use. 16.4.3.3. Control strategy of energy storage for system voltage regulation
Control strategy of energy storage for system frequency regulation ESS has a fast power response speed, and be used to generate virtual inertia for primary frequency control, which increases the stability of system frequency with large-scale grid-connected PV generation.
Energy storage systems are essential to the operation of electrical energy systems. They ensure continuity of energy supply and improve the reliability of the system by providing excellent energy management techniques. The potential applications of energy storage systems include utility, commercial and industrial, off-grid and micro-grid systems.
Therefore the ESS capacity can be allocated reasonably to restrain the power fluctuation of the PV station and improve the stability of the power system. Hence, The ESS is optimized used. Figure 16.13. Grid-connected control strategy of energy storage system based on additional frequency control.
Energy storage systems are relatively new units in microgrids or power distribution systems following in the wake of increased installation of renewable energy generation in the twenty-first century. One typical feature of renewable energy generation is the inherent nature of uncertainties.
In the new system, a power flow controller is adopted to compensate for the NS, and a super-capacitor energy storage system is applied to absorb and release the RBE. In addition, through the cooperation of each part, the proposed power supply system can provide continuous power without neutral sections.
