Abstract

Parallel-connected inverters play a crucial role in the grid interface of distributed generation. The world is now moving towards sustainability, while shifting from traditional power systems to renewable energies. With the emergence of microgrids as an alternative for an uninterruptable power supply, there are significant challenges in terms of control strategies. Ensuring stability and reliability in electrical systems amidst the integration of diverse energy sources with varying power ratings into a distribution network presents the need for advanced control techniques. These techniques must effectively maintain power system quality, stability, and reliability when operating in microgrids with parallel-connected inverters. Achieving accurate power sharing under different operating conditions, compensating for voltage and frequency deviations, and maintaining a well-controlled microgrid system are essential objectives. This paper focuses on the categorization of droop-based control with multi-loop insertion approaches. Additionally, it provides a comprehensive analysis of inverter-based microgrid control techniques, emphasizing power-sharing accuracy in various conditions, and presents a detailed comparison of different control strategies.
