MPPT and Dead-Beat Control for Power Management of Hybrid Micro-Grid Applications

Abstract

This paper introduces the active and reactive power technique for power management using a single phase inverter connected with the utility grid and maximum power point tracking (MPPT) for renewable energy sources, such as Wind-Turbine (WT) and Photovoltaic (PV) panels. In this study, the dead-beat control algorithm is utilized to control the active and reactive power injected into the grid. The dead-beat control algorithm is based on discretized equations in (α-β) stationary reference frame transformation. Resistive and inductive loads are connected with the micro-grid system, and illustrated their influence on the performance of the inverter.The maximum power point tracking algorithm is introduced to insure the most utilization of the available powers to feed the required loads and the grid power, as a part of the proposed management system. The overall system has been simulated and tested for operation with hybrid wind and PV sources,for different modes of operation under variations of PV irradiance and wind speed.
