VRE Integrating in PIAT grid with aFRR using PSS, MPPT, and PSO-based Techniques: A Case Study Kabertene

Abstract

The Fluctuations in demand and weather conditions have a significant impact on the frequency and the voltage of Algeria's isolated PIAT power grid. To maintain stability and reliable power supply, it is crucial to keep these quantities close to their expected levels. An automatic (FRR) is employed to regulate real-time frequency deviations caused by integrating variable renewable energy (VRE), specifically wind and solar power in the Kabertene region. In order to mitigate wind power fluctuations, a power system stabilizer is implemented, which helps dampen oscillations. The use of Maximum Power Point Tracking (MPPT) techniques optimizes the extraction of power from solar panels under varying conditions. For efficient scheduling and dispatch of VRE generation, particle swarm optimization (PSO)-based algorithms are used. These algorithms ensure optimal utilization of renewable energy sources by considering their intermittent nature. This study proves the effectiveness of these techniques in enhancing grid stability, reducing frequency deviations, and improving VRE integration. Valuable insights are provided on their practical implementation, playing a crucial role in transitioning to a cleaner and more sustainable energy system.

A deep dive into enhancing frequency stability in integrated photovoltaic power grids

“…Frequency fluctuations in electrical systems can result from imbalances between power generation and load demand, potentially leading to synchronization issues among grid-connected devices and undermining system stability [13]- [17]. To maintain the desired frequency levels, grid operators must diligently monitor and regulate system frequency, relying on effective frequency control mechanisms and feedback systems [18].…”

Robust hybrid control strategy for active power management in Kabertene wind farm within Algeria’s PIAT grid

“…Regarding the 153 GWh of annual energy demand anticipated in 2023, VRE sources are anticipated to provide 18.67% [5]. The considerable dependence on renewable energy sources possesses the capacity to generate noteworthy ecological advantages, such as diminished carbon emissions [6], fortified environmental safeguarding, and enhanced energy accessibility for nearby communities [7]- [9].
