Recent advancements in the integration of solar energy into power distribution systems are paving the way for improved power quality and efficiency. A study led by Dinanath Prasad from the Department of Electrical Engineering at Delhi Technological University has introduced innovative stochastic-gradient-based adaptive control algorithms aimed at enhancing power quality in photovoltaic (PV) integrated three-phase distribution systems. The research, published in ‘IET Generation, Transmission & Distribution’—which translates to ‘IET Generation, Transmission & Distribution’—could have significant implications for the commercial energy sector.
The study focuses on four distinct algorithms: least mean square (LMS), least mean fourth (LMF), sign-error LMS, and ε-normalised LMS (ε-NLMS). These algorithms are designed to estimate fundamental load current, a critical factor in maintaining stable power delivery. “By employing these adaptive control strategies, we can significantly improve reactive power compensation and ensure better load balancing,” Prasad stated, highlighting the potential for these technologies to optimize energy distribution.
One of the standout features of this research is its implementation of the hysteresis current control (HCC) technique, which generates switching pulses for a three-phase Distribution Static Power Compensator (DSTATCOM). This technology is crucial for managing power quality, especially under non-linear load conditions, which are increasingly common in modern energy systems. The inclusion of Maximum Power Point Tracking (MPPT) ensures that solar PV arrays deliver maximum power, further enhancing the system’s efficiency.
The research was validated both in a MATLAB/Simulink environment and through experimental setups, demonstrating its practical applicability. As the energy sector grapples with the challenges of integrating renewable sources into existing grids, such advancements could lead to more reliable and efficient energy systems. “Our goal is to meet the standards set by IEEE-519, which emphasizes the need for high power quality in electrical systems,” Prasad added, underscoring the importance of regulatory compliance in the commercial landscape.
As industries increasingly prioritize sustainability, the findings from Prasad’s research could drive the adoption of smarter grid technologies and adaptive control systems. This shift not only promises to enhance the reliability of power supply but also supports the broader transition towards renewable energy sources, potentially leading to significant cost savings and improved environmental outcomes for businesses.
