Advanced Constant Active Power and Inertia Control of Wind Power System with Supercapacitor Energy Storage System

This paper presents an enhanced approach to managing a Double Fed Induction Generator (DFIG) wind turbine with a Supercapacitor (SC) energy storage system. The focus is on achieving constant active power and inertia control. The technique involves linking the supercapacitor to the DC link of the DFIG converters to achieve the desired constant wind active power control. Moreover, the impact of Virtual Inertia (VI) support via the Energy Storage System (ESS) and rotating mass of DFIG is investigated. The study includes a detailed analysis of two simulation scenarios, highlighting the respective advantages and limitations of each approach.
