Power flow control based on bidirectional converter for hybrid power generation system using microcontroller

摘要

Energy flow management of photovoltaic (PV) based ON-Grid system using BDC converter is analysed and implemented in this paper. The intermittent nature of renewable energies makes the unstable operation of utility grid system. In order to ensure the stable operation of the utility grid system and to support smart grid functionalities, there is the requirement of power electronics participation is high. So that, Grid-connected PV with converters plays an essential role in power management. In this paper, a suitable bidirectional converter (BDC) with advanced optimization control strategies has proposed for power flow management. Further this converter provides a high efficiency, enhanced control flexibility and has the capability to operate in different operational modes from the input to output. The power from PV and grid satisfies the load demand and maintains the continuous power flow to load. The power balance improvement in BDC has power factor correction, harmonics elimination and voltage regulation at AC mains. This paper proposes the analysis of Genetic Algorithm tuning PID (GA-PID) control a process that effectively reduces the bidirectional converter harmonics; this aim is attained and shown in both MATLAB/Simulink and experimental results.
