Photovoltaic Integration on Distribution Networks: Harmonic Mitigation With Passive Filters
(Institute of Electrical and Electronics Engineers Inc., 2025) Celik, D.; Yucel, Y.A.; Goyal, S.K.
The integration of solar photovoltaic (PV) systems has become crucial for modern power generation, offering significant environmental and technical benefits. However, high penetration of PV systems into electricity distribution grids can present operational challenges, including reverse power flow, voltage fluctuations, and harmonic distortions. This paper investigates the impact of PV energy systems and static nonlinear loads (NLLs) on grid performance, with a focus on power quality, voltage stability, and harmonic mitigation. The study uses single-tuned passive filters (STPF) as a solution to reduce harmonic distortions caused by nonlinear loads, thereby enhancing overall power quality. A detailed simulation of the PV distribution grid, incorporating both PV systems and static loads, is conducted using ETAP software to assess system performance under different operational scenarios. The findings highlight the need for effective integration strategies to ensure grid stability and power quality in the presence of renewable energy sources and NLLs. © 2025 IEEE.
Strategic Deployment of Hydrogen With Nuclear-Renewable Synergy: Pathways to Carbon Neutrality and Sustainable Development Goals
(Institute of Electrical and Electronics Engineers Inc., 2025) Çelik, D.; Goyal, S.K.
This work explores the combination of nuclear-renewable hybrid systems and hydrogen production as a pathway to reach carbon neutrality and support the objectives of sustainable development goals (SDGs). The proposed system integrates nuclear energy, a photovoltaic (PV) system, and wind energy to deliver a consistent and dependable clean energy supply. The assessment examines the system's economic viability by analyzing critical financial indicators, including NPV and IRR, under different scenarios. These scenarios include revenue from both energy production and hydrogen and oxygen sales, which significantly enhance profitability. This study highlights the synergy between wind and PV power, where their complementary generation patterns - wind often peaking at night and solar during the day - reduce variability and maximize energy utilization. Hydrogen integration further strengthens financial performance by adding flexible energy storage and offering additional revenue streams from hydrogen sales, especially during periods of excess energy generation. This enhances grid stability, reduces curtailment, and supports decarbonization efforts. The results highlight the critical role of well-designed policy frameworks, financial incentives, and technological progress in reducing expenses and tackling key obstacles, including the substantial upfront investments and infrastructure needs associated with hydrogen production and storage. © 2025 IEEE.
