Abstract:
In several countries, grid operators have started to introduce novel reserve market products that are technology-open and allow power electronic converter interfaced assets, such as BESS or UPS systems, to provide ancillary services. In this paper, the provision of frequency control and virtual inertia with a double conversion UPS is demonstrated. A novel control algorithm is presented that emulates inertia accurately without calculation of the frequency derivative. The algorithm is tested in the laboratory on a 250 kW unit of ABBs recently launched modular UPS system MegaFlex.
