“…Furthermore, complex optimization of UC and ED can be solved with semidefinite programming [213]. • Advanced Control Approaches: Several control approaches are also presented in the literature to handle the uncertainties stem from the variation of wind speed and solar irradiation [214], [215]. The presented control approach in [215] combines the virtual inertia concept and pitch angle control to dynamically shift the maximum power tracking curve of DFIG wind generation system.…”

The utilization of renewable energy sources (RESs) has become significant throughout the world, especially over the last two decades. Although high-level RESs penetration reduces negative environmental impact compared to conventional fossil fuel-based energy generation, control issues become more complex as the system inertia is significantly decreased due to the absence of conventional synchronous generators. Some other technical issues, high uncertainties, low fault ride through capability, high fault current, low generation reserve, and low power quality, arise due to RESs integration. Renewable energy like solar and wind are highly uncertain due to the intermittent nature of wind and sunlight. Cutting edge technologies including different control strategies, optimization techniques, energy storage devices, and fault current limiters are employed to handle those issues. This paper summarizes several challenges in the integration process of high-level RESs to the existing grid. The respective solutions to each challenge are presented and discussed. A comprehensive list of challenges and solutions, for both wind and solar energy integration cases, are well documented. Finally, the future recommendations are provided to solve the several problems of renewable energy integration which could be key research areas for the industry personnel and researchers.

“…MGs are more reliable, sustainable and having limited power losses while fulfilling the load demand [1]. Occasionally, MG encounters oscillation in their power output, causing system voltage and frequency deviation when connected to non-dispatchable renewable energy sources such as wind power generator [2][3][4]. This problem is usually addressed by installing dispatchable power sources such as a bank of batteries called the battery energy storage system (BESS) and fuel cell [5][6][7].…”

“…To improve the stability of the system frequency, domestic and foreign scholars have performed much research on single-WT frequency regulation strategies in recent years. In [3]- [7], frequency deviation and frequency change rate signals are introduced into the active control loop of a WT, and the rotational kinetic energy inside the rotor of the WT is used to respond to system frequency variations, which enhances the inertial response capability of the system. In [8]- [12], rotor overspeed operation and pitch operation are separately adopted to reduce the power-wind speed curve of the normal operation of a WT, leaving room for system frequency regulation.…”

When a large amount of wind power is connected to the power grid, certain control methods need to be taken for wind turbines (WTs) so that WTs can respond to system frequency changes and maintain system frequency stability. Based on the frequency control method of a single doubly fed induction generator, a deloading power coordinated distribution method for frequency regulation by wind farms considering wind speed differences is proposed to better utilize the wind farm frequency regulation ability. A reasonable distribution of the deloading power of a wind farm for participation in grid frequency regulation to better utilize the wind farm frequency regulation ability. A quantitative calculation formula for the wind speed, total deloading power and single WT deloading power is established by using a variable parameter deloading power coordinated distribution coefficient based on the wind speed. The deloading power is distributed according to the wind speed of the WT units to adapt to the wind speed distribution differences between WTs in cluster wind farms and fully utilize the wind farm frequency regulation ability. A typical doubly fed induction generator (DFIG) wind farm is used as a simulation case. The experimental results show that the control strategy can distribute the output of each WT, improve the frequency response of the wind farm and enhance the frequency stability of the system.
