TY  - JOUR
AB  - The inertia of future power systems is expected todecrease with increasing penetration of renewable energyresources. Sufficient inertia is required to avoid large fluctuationsin grid frequency and also limit the excessive rate of change offrequency (RoCoF). Unlike many previous works focusing onvirtual inertia on the power supply side, this paper studies andquantifies potential virtual inertia from the load side. The analysisshows that, voltage-dependent loads coupled with electric spring(ES) technology can be operated as smart loads (SL) within the +/-5% tolerance of the ac mains voltage and offer virtual inertia.Following the U.K. National Grid frequency requirements, it isshown that the ES based SL can provide virtual inertia up to aninertia coefficient of HSL=2.5 s (when np=2) with respect to its loadpower rating. The effectiveness of such virtual inertia extractionfrom SL has been verified by the simulation study on a CIGREbenchmark microgrid with high-resolution domestic demandmodel. The value of HSL is shown to be around 1.3 s during themost part of the day and can increase the overall system inertiacoefficient by 0.53 s if all the domestic loads are transformed intothe proposed smart loads.
