“…When the electric vehicle's battery is being charged, it is possible to achieve down-regulation, and when the battery is being discharged, it is possible to achieve up-regulation [109] for frequency control. In [110,111], a vehicle-to-grid (V2G) frequency regulation service is provided by the battery of the EV for a microgrid system consisting of wind generators. In most cases, the EV battery cannot alone participate the frequency regulation.…”

A paradigm shift in power systems is observed due to the massive integration of renewable energy sources (RESs) as distributed generators. Mainly, solar photovoltaic (PV) panels and wind generators are extensively integrated with the modern power system to facilitate green efforts in the electrical energy sector. However, integrating these RESs destabilizes the frequency of the modern power system. Hitherto, the frequency control has not drawn sufficient attention due to the reduced inertia and complex control of power electronic converters associated with renewable energy conversion systems. Thus, this article provides a critical summary on the frequency control of solar PV and wind-integrated systems. The frequency control issues with advanced techniques, including inertia emulation, de-loading, and grid-forming, are summarized. Moreover, several cutting-edge devices in frequency control are outlined. The advantages and disadvantages of different approaches to control the frequency of high-level RESs integrated systems are well documented. The possible improvements of existing approaches are outlined. The key research areas are identified, and future research directions are mentioned so that cutting-edge technologies can be adopted, making the review article unique compared to the existing reviews. The article could be an excellent foundation and guidance for industry personnel, researchers, and academicians.

“…In addition to the scenarios presented in [5], a new situation has been introduced with a lower demand, and therefore lower inertia, named Pmin and presented in Table I, while the wind data [6] is presented in Table II. The wind data used has a very high time-resolution, at 25 samples/s, and was taken at a location close to the shore without any significant geographic accident disturbing the wind.…”

“…For each average wind speed (around 5 m/s for w1 and w4 and 10 m/s for w2 and w5), two different wind profiles have been selected, one with low TI (w1 and w2) and tow with high TI (w3 and w4). The behaviour of the system under the studied wind profiles and the reference load scenario was presented in [5]. The extension of the same strategy to the Pmin scenario, with much lower inertia, leads to unacceptable frequency oscillations which are exposed in the next section.…”

“…The studied system is based on the electric power system of the island of San Cristóbal, in Galapagos (Ecuador) and consists of up to three 800 kW wind turbines, up to three diesel generators, rated at 813 kVA each [3] and a maximum demand of 2.9 MW [4] The effect of passive components such as transformers or lines has been neglected. More details of this system, including parameters, can be found in [5].…”

The reduction in inertia present in electric power systems due to the increase in renewable generation interfaced with power converters presents various challenges in power system operation. One of these challenges is keeping the frequency of the system within acceptable bounds, as the reduced inertia allows faster changes in frequency. A possible way to mitigate this effect is to introduce a certain degree of frequency response in the demand side, in such a way that a loss in generation leads to a decrease in the demanded power, levelling the generation-demand balance. In this paper, one limitation of this approach is analysed, specifically the case where the demand response is excessive to the system inertia and demand, producing fast frequency oscillations. A scenario where this happens, on a simulated islanded system based on the electric power system of the island of San Cristóbal, in Galápagos (Ecuador), is studied, and a method of detecting these oscillations is proposed, as a first step to develop an appropriate response to them.
