In recent, renewable energy has received considerable attention worldwide due to the ‘Global Warming of 1.5oC’. There are still many challenges to be solved, however, to increase the penetration rate of renewable energy in the power system. Above all, most of the renewable energy DGs even aggravate the grid voltage from the intermittency of variable renewable energy sources rather than regulate the voltage as the conventional generators did. This paper proposes power-sensitivity-based STATCOM operation to minimize grid impact from measurement noise. The proposed method realizes seamless control of the voltage by compensating with the reactive power when the power generation or load consumption is changed. To achieve the proposed method, the reactive power references of the STATCOMs are operated based on the power sensitivities. As the result, it can be accomplished that constant voltage control even if high penetration of renewable energies. The proposed method is verified with several case studies that are based on a microgrid with practical data from a real island power system. The verification is carried out using the power system computer aided design and electromagnetic transient including DC (PSCAD/EMTDCTM) simulation software.
