Harmonics and interharmonics estimation of wind power plant using sliding window matrix pencil

Wind power plant is source of harmonics and inter-harmonics. Estimation of these harmonics is very important and crucial task in modern distribution generation environment. This paper presents sliding window matrix pencil algorithm to estimate harmonics and inter harmonics produced by doubly fed induction generator based wind power plant. The series of simulation results under variable wind speed is performed to show the effectiveness of proposed algorithm and its performance is also compared with sliding widow ESPRIT.
