“…Since the fundamental concept of VSMs was formally introduced, it has been subject of several publications. Most of the research deals with specific issues on the implementation of VSMs such as: the necessary requirements of the PEI to perform a VSM [3], selection of the storage media [4], laboratory prototypes for experimental tests [5] and an optimal virtual inertia controller for wind generator [6].…”

This paper presents a load frequency control (LFC) by using distributed energy storage systems (ESSs) and plug-in electric vehicles (PEVs) in a large power system with MW-level distributed PV generation. The ESSs are controlled to mimic virtual inertia. Controls are done in two levels: central and local. An optimal virtual inertia is calculated considering the total PV power variation in a control area. Based on this, central ESS power command is decided and by coordination, this central ESS power command is distributed to the local ESSs to emulate the optimal virtual inertia. PEVs are used for the LFC considering user convenience, availability and state of charge (SOC) of the batteries. Effectiveness of the proposed method to provide LFC is verified by numerical simulation results.

“…Thus, the inverter behaves as a current-controlled voltage source inverter [13,48]. This topology is used by the European VSYNC research group [45,50] and has demonstrated the effectiveness of inertia emulation using VSG topology through real-time simulations [51] and several field tests [52]. In [22], an experimental verification of the topology is presented for remote microgrid applications.…”

Virtual Inertia: Current Trends and Future Directions

Abstract:The modern power system is progressing from a synchronous machine-based system towards an inverter-dominated system, with large-scale penetration of renewable energy sources (RESs) like wind and photovoltaics. RES units today represent a major share of the generation, and the traditional approach of integrating them as grid following units can lead to frequency instability. Many researchers have pointed towards using inverters with virtual inertia control algorithms so that they appear as synchronous generators to the grid, maintaining and enhancing system stability. This paper presents a literature review of the current state-of-the-art of virtual inertia implementation techniques, and explores potential research directions and challenges. The major virtual inertia topologies are compared and classified. Through literature review and simulations of some selected topologies it has been shown that similar inertial response can be achieved by relating the parameters of these topologies through time constants and inertia constants, although the exact frequency dynamics may vary slightly. The suitability of a topology depends on system control architecture and desired level of detail in replication of the dynamics of synchronous generators. A discussion on the challenges and research directions points out several research needs, especially for systems level integration of virtual inertia systems.

“…The provision of emulated inertia from power electronics interfaced storage and generation has gained attention in recent years, through for example virtual synchronous machine-type controls [12,13] of the power electronics converters. Providing an inertial response typically requires short-term energy storage, and it has been investigated for energy storage systems (ESS) such as batteries, supercapacitors, and flywheel storage in [14][15][16][17][18][19] and for photo-voltaic systems operating off their maximum power point [20]. For wind turbines, the stored kinetic energy in the turbine rotor can be used in combination with VSMcontrol, as shown in [21][22][23].…”

Virtual Inertia Control of Variable Speed Heat Pumps for the Provision of Frequency Support

The growth in the integration of converter interfaced renewable energy has reduced the system inertia, which threatens system stability due to high rate of change of frequency (RoCoF) and frequency nadir issues unless steps are taken to mitigate it. There is a need to provide sufficient fast frequency response to maintain adequate inertia in the system. This paper investigates the capabilities of a variable speed heat pump to provide an emulated inertial response. This paper presents a virtual synchronous machine control for a variable speed heat pump that provides support for grid frequency regulation over the inertial response time frame. A small-signal model with the transfer function of the variable speed heat pump is developed to analyse the effectiveness and feasibility of providing virtual inertia at the device and grid level, respectively. Furthermore, the small-signal model is validated using hardware in the loop simulation. Finally, the aggregated frequency response and virtual inertia contribution by a population of the heat pumps are evaluated and quantified in an urban distribution system.
