The AGC (automatic generation control) reserve capacity requirement in a gird with high photovoltaic (PV) power penetration is much higher than that in a traditional grid in order to address the rapid PV p.
According to the above literature, most of the existing control strategy of energy storage power stations adopt to improve the droop control strategy, which has a great influence on the system stability and cannot be controlled again in case of blackout.
However, the ESUs are mostly integrated in distributed PV power plants in the previous research. Actually, if integrated energy storage station (BESS) is adopted by the power grid operator, it will be more effective to address the PV power fluctuation that can seriously increase the AGC reserve capacity.
The energy storage power station is dynamically distributed according to the chargeable/dischargeable capacity, the critical over-charging ES 1# reversely discharges 0.1 MW, and the ES 2# multi-absorption power is 1.1 MW. The system has rich power of 0.7MW in 1.5–2.5 s.
Due to the disordered charging/discharging of energy storage in the wind power and energy storage systems with decentralized and independent control, sectional energy storage power stations overcharge/over-discharge and the system power is unbalanced, which leads to the failure of black-start.
Aiming at the problem that wind power and energy storage systems with decentralized and independent control cannot guarantee the stable operation of the black-start and making the best of power relaxation of ESSs, a coordinated control strategy of multi-energy storage supporting black-start based on dynamic power distribution is proposed.

This review presents a state-of-the-art literature review of Automatic Generation Control (AGC) control strategies for power systems containing renewable energy sources. The incorporation of renewable energy into the power system has a large impact on the stability, reliability, economy and security of the power system.
The concept of automatic generation control has an immense role in providing quality power in an interconnected system. To obtain quality power by controlling the oscillations of frequency and tie-line power, a proper controller design is necessary.
The aim of this paper is to study the automatic generation control (AGC) in a restructured power system. The power system under study has five different diversified energy sources assisting some real time nonlinearities like generation rate constraint (GRC), governor dead band (GDB), and boiler dynamics.
Because of the uncertainty of the external environment, high penetration of renewable energy such as wind power and solar energy in the modern power system renders the traditional automatic generation control (AGC) methods more challenging.
Modern power systems must be resilient to sudden load variations in order to keep the system stable. For Automatic Generation Control (AGC), single load change is impractical and need further analysis.

Most wind turbines need a minimum wind speed of about 7 to 11 mph (3 to 5 m/s) to start generating electricity. This threshold, called the “cut-in speed,” is the point where the blades begin spinning fast enough to produce usable power.

The conventional controllers are the most commonly used in small wind energy conversion systems. These usually consists of a PID/PI controller for rotor speed and generated power control. These controllers are more suitable for small WT systems.
