A Split-Pi Technique-Based Adaptive Droop Control Method for Microgrid Control

DC microgrids (MGs) are gaining popularity as efficient solutions for integrating diverse energy resources. Traditionally, droop control has been widely used as a decentralized control method for distributing power in DC MGs. This paper introduces a new approach by implementing an Adaptive Dropping-based Split range control using an Proportional-integral controller which involves the use of two valves, a big valve and a small valve, to effectively control the underlying process and also explores the topology and operational characteristics of an adaptive drooping-based Split-Pi pulse generated fed DC-DC power converter. The Split-Pi pulse generated fed DC-DC converter was utilized to obtain results for battery charging or EV applications. Feed-forward control is used to show how to regulate the gain of the Split-Pi pulse-generated fed DC-DC converter by directly computing the necessary converter gain. In this paper PV inputs converter based on the Adaptive Drooping technique is developed to make a simulation circuit for an input of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12\ V</tex> from the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">PV</tex> panel and an output voltage of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">42\ V</tex> across the load for the battery charging and discharging circuits. Utilizing Split-PI in droop control enhances the stability of the microgrid system in comparison to high gain. Compared to the traditional PI controller, the dynamic response of the microgrid system is enhanced, resulting in increased stability.
