In the sun-drenched regions of Uzbekistan, a silent revolution is underway, powered by solar photovoltaic installations. As these systems integrate with the low-voltage electric grid, they bring not just clean energy, but also a unique set of challenges. Isroil Yuldoshev, a researcher from Tashkent State Technical University and Tashkent University of Applied Sciences, has been delving into these issues, with findings recently published in the Proceedings of the International Conference on Innovative Applications in Information Technology.
Yuldoshev’s work focuses on the operational intricacies of photovoltaic power plants (PVPP) and their interaction with the low-voltage grid. Using a two-channel flat-panel oscilloscope, he measured voltage, current, and frequency fluctuations in the grid, identifying significant voltage deviations, particularly during winter. These fluctuations, he found, were causing frequent disconnections and reconnections of grid inverters, a critical component in PVPPs.
“The instability in voltage phases, losses in the electrical network, and even incorrect grounding of the inverter were identified as key culprits,” Yuldoshev explained. His research didn’t stop at diagnosis; he developed and created additional protective equipment for inverters, designed to be reliable, automated, and using components readily available in the domestic market of Uzbekistan.
The implications of Yuldoshev’s work extend beyond Uzbekistan’s borders. As solar power continues to boom globally, the integration of PVPPs with low-voltage grids is becoming increasingly common. The issues identified by Yuldoshev are not unique to Uzbekistan, and neither are his solutions. His work could potentially shape future developments in the field, ensuring smoother integration and more stable operations of solar power systems worldwide.
Moreover, the commercial impacts of this research are substantial. By addressing these technical challenges, Yuldoshev’s protective equipment could enhance the efficiency and reliability of solar power systems, making them more attractive to investors and energy providers. This could accelerate the transition to renewable energy, benefiting both the environment and the economy.
In the rapidly evolving energy sector, Yuldoshev’s research serves as a reminder of the importance of addressing technical challenges head-on. As he puts it, “Understanding and mitigating these issues is crucial for the sustainable growth of solar power.” With his innovative solutions, he is not just contributing to the academic discourse but also paving the way for a brighter, more sustainable future.
