14 - H-infinity-based microgrid state estimations using the IoT sensors

Abstract

This chapter proposes an H-infinity-based microgrid state estimation algorithm. First of all, the renewable microgrid is represented by the state-space framework. For doing this, the renewable distributed energy resource such as solar panel is connected to the IEEE-4 bus distribution power system. Then the internet things (IoT)-based smart sensors are used to obtain the system measurements. The energy management system adopts the H-infinity-based state estimation algorithm where it will no need to know the exact noise statistics. The simulation is conducted with and without sensor faults as well as large disturbance conditions. It demonstrates that the H-infinite can effectively estimate the system states under sensor fault and large disturbance conditions.
