EASI algorithm based load profile estimation for microgrid

Abstract

Researches on the control of inverter based microgrid, multi-agent based microgrid, and decentralized control of distributed generation have attracted more and more attention. It is also important to touch the field of load estimation of microgrid because microgrid can operate more efficiently with the knowledge of load under the mode of utility grid connected or islanding mode. Consequently, EASI (Equivariant variant Adaptive Separation via Independence) algorithm has been presented to figure out it, which is one kind of blind source separation methods. Further simulation on IEEE 9 bus system shows that it can accomplish the task of estimating load profile well without the knowledge of network parameters.
