Optimize Ranking and Load Shedding in Microgrid Considering Improved Analytic Hierarchy Process Algorithm and Power Stability Index

open access: yesMathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023
This paper proposes a load shedding model for the island microgrid based on the ranking of loads and the power stability index (PSI). Loads are ranked based on the improved analytic hierarchy process (AHP) algorithm. Real‐time measurement systems have the function of collecting data for very important, important, and less‐important loads at each bus ...

Developing Control Strategy for PV‐Based Distributed Generator for Enhancing Frequency Regulation of Microgrid

open access: yesMathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023
This paper presents a control strategy for a photovoltaic (PV)‐based distributed generator (DG) to enhance the frequency regulation of a microgrid. A microgrid is a small‐scale power system that integrates distributed energy sources and interconnected loads, which can operate independently or in parallel with the main grid.
