Abstract

To maintain a dependable and sustainable power supply in a microgrid system, it is crucial to combine renewable energy sources with hybrid energy backup. To achieve maximum output power from solar source, a high gain DC-DC boost converter is managed using the dual Kalman filter based perturb and observe approach. A sliding mode current controller at a three phase inverter with an LC filter is intended to follow an undisturbed reference voltage. To effectively manage the power flow and optimize the utilization of available resources, a robust power management algorithm is required. The novel power management algorithm for a solo operated renewable distribution generation unit with hybrid energy backup in a microgrid is introduced. The algorithm aims to dynamically allocate power among various sources, storage systems, and loads, considering their characteristics and the overall system constraints. The algorithm utilizes sliding mode control techniques to regulate the current flow from the renewable generator and effectively manage the power allocation among different energy sources, storage systems, and loads.

Abstract

Renewable source penetration into the distribution grid is merely a greater challenge as the powers from renewable sources are not stable and constant. Due to their sporadic operating states the power shared to the grid creates power quality issues. Therefore, an efficient adaptive PMA needs to be adopted for the control of these renewable sources, which controls the power extraction of these sources. For standard power sharing to the variable loads in the grid islanding state, the renewable sources are updated with the ESS module. In this paper, a low-rating distribution test system is considered connected with different renewable sources PV sources, wind farms, and fuel cell plants sharing renewable power. The PV source module is updated with AF-PID replacing the PI controller integrated PMA and ESS module for extensive control of the power of the generation unit during any operating condition. The DC and AC voltages are more stabilized by the upgraded PMA during grid islanding conditions. Mitigation of ripple and harmonic content is achieved by the AF-PID controller varying the proportional, integral, and derivative gains as per the error signal generated. A comparative analysis is carried out on the system validating the effectiveness of the AF-PID controller using MATLAB Simulink software.
