This paper proposes a new approach for virtual inertia emulation which eliminates the counteractive action of inertia. A frequency response model is also proposed which
A novel method is used for extracting virtual inertia support from both energy storage system (ESS) and solar PV. Frequency stability of the microgrid system improves under variable load condition. Different levels of RES penetration are considered for testing the effectiveness of proposed work.

To overcome this problem, virtual inertia is introduced to ensure the short-term frequency stability of the grid. Generally, frequency control should be done in three stages: Inertial response (response to the rate of change of frequency) Primary frequency control. Secondary frequency control. To achieve proper inertial response, the required

According to Tarnowski et al. [10], WTs can provide an inertial response by extracting the kinetic energy stored at their rotational mass with approximate inertia constant of 3.5 s [11]. Nevertheless, WTs require power electronics sensitive to frequency changes to allow WTs to adapt their power reference based on frequency measurements

Energy storage technologies have emerged as a viable alternative to providing inertia through virtual inertia, i.e. inertia generated or simulated with power
To demonstrate, let''s look at how the Dalrymple Battery Energy Storage System (BESS), currently the only source of virtual inertia on the National Electricity Market (NEM) responded during the South Australia separation event on the 16/11/2019 at 6:05pm (discussed earlier on WattClarity).).
Although RESs are inherently inertia-less, they can be enabled to deliver synthetic or virtual inertia by emulating the inertial response of an SG using a controller [35]. Approximately 20% to 30% of the inertia embedded in the distribution system in the UK is invisible to transmission system operators [15], [82] .

The Energy Storage System (ESS) is one solution to facilitate the integration of RES by storing or releasing energy immediately in response to the system needs. A large-scale ESS is able to replace the spinning reserve capacity of conventional generators and hence reduces the carbon emissions.

On the other hand, an SC is a modern energy storage device that can be used for producing inertial power to improve the frequency response of low-inertia PSs [22–25]. SC banks are integrated with RP generating systems as alternative storage devices for conventional lead-acid batteries.
As the world strives toward meeting the Paris agreement target of zero carbon emission by 2050, more renewable energy generators are now being integrated into the grid, this in turn is responsible for frequency instability challenges experienced in the new grid.

In modern power systems, conventional energy production units are being replaced by clean and environmentally friendly renewable energy resources (RESs). Integrating RESs into power systems presents numerous challenges, notably the need for enhanced grid stability and reliability. RES-dominated power systems fail to meet
This kinetic energy is used as an inertia response in the range 2–6 s [29]. Generally, there are two types of inertia response; one loop inertia response and two-loop inertia response. In the former, one loop control based on the ROCOF is used to release the kinetic energy stored in the rotating blades, while the latter uses two loops based on
