An Efficient Quantum-Enhanced Ensemble Fault Detection for Solar Energy Integration using an Iterative Game-Theoretic Approach with Adaptive Neuro-Fuzzy Inference and Energy Storage

Shreyas Hole — 2025-03-14

The rising energy requirements across the globe coupled with the need for sustainable development makes it imperative to harness renewable sources such as solar energy. That being said, changes in the weather and instability in the systems can enhance the reliability and efficiency of solar power systems which in the case of the current systems poses quite a challenge. The current solar power systems cannot adapt to such changes therefore causing energy wastages as well as problems with the grid. The new model presented here, the Ensemble Fault Detection Model for Solar Deployments (EFDMSD), uses technology to resolve a number of issues. This model has been built to harvest solar energy with greater speed and accuracy by means of Quantum Machine Learning (QML). A system’s changes can be addressed appropriately in real-time, thanks to the model’s Adaptive Neuro-Fuzzy Inference Control’s (ANFIS) control system. In other words, Game Theory is applied to explain energy shortage scenarios better and manage supply for peak periods. Energy Storage Systems are also present within the mix which allows for excess solar energy to be accumulated making the supply of energy more secure. These techniques, as a result of using artificial intelligence, are able to enhance energy production, stabilize grids, and optimize performance for many hardware configurations. With the implementation of the EFDMSD model, the availability and reliability of energy through the use of simpler solar systems is enhanced. Hence, there would be changes in the economic impacts while reducing the grid impact thus leading the country towards clean energy.

Navigating Renewable Energy Transition Challenges for a Sustainable Energy Future in Ghana

Mark Nyasapoh — 2025-03-06

The transition to a sustainable energy future in Ghana faces critical challenges, particularly in integrating renewable energy sources like solar and wind into the national grid. This study examined Ghana’s progress in renewable energy adoption using the International Atomic Energy Agency’s (IAEA) Model for Energy Supply Strategies and Their General Environmental Impacts (MESSAGE) tool. It evaluates the feasibility of achieving the 10% renewable energy target set in national energy policies by 2030 and beyond, highlighting key challenges and their impact on the country’s energy transition efforts. The findings revealed a significant shortfall, with renewable energy penetration reaching only 4.77%, far below the targeted 10%. The actual installed capacity of renewable energy sources ranges from 150.87 MW to 377.18 MW, falling considerably short of the projected 219.75 MW to 645.71 MW from 2020 to 2050, respectively. Expanding Ghana’s renewable energy sector remains challenging, with fossil-based thermal generation continuing to dominate, raising concerns about emissions and sustainability. Overcoming barriers to renewable energy penetration requires targeted policies, investment in energy storage, smart grids, and financial incentives. Additionally, integrating renewables with low-carbon baseload options like Small Modular Reactors (SMRs) could accelerate Ghana’s energy transition. Achieving a sustainable energy future will depend on strong governmental commitment, private sector involvement, and technological innovation to bridge the gap between energy targets and actual capacity while significantly creating jobs.

Transient Stability Enhancement in Microgrids:

Siradj Younes — 2025-03-04

The widespread integration of renewable energy sources, such as photovoltaic (PV) and wind power, poses significant challenges to power system stability. This study investigates the combined effect of a Power System Stabilizer (PSS) and a Static Var Compensator (SVC) in enhancing transient stability during sequential symmetrical and asymmetrical faults. A modified IEEE 9-bus system was used, with PV arrays connected to Buses 5 and 6 and a wind farm integrated at Bus 8. Simulations were conducted using ETAP 20.2, with Critical Clearing Time (CCT) calculated and frequency/voltage variations analyzed.

The results demonstrate that the coordinated use of PSS and SVC significantly improves system stability, increasing CCT values and damping critical oscillations. The system showed enhanced resilience to sequential faults, providing practical solutions for renewable energy integration challenges. The key conclusion is that PSS-SVC coordination effectively enhances the flexibility of power systems under high renewable energy penetration.

Techno-Economic Analysis of Solar Energy Developing Technologies in Libyan Residential Communities

Salamah Ihfedah — 2025-01-29

These days, renewable energy is becoming increasingly vital. Renewable energy sources that are widely used include biomass, geothermal, wind, solar, and hydroelectric power. Because solar energy is sustainable, inexpensive to operate, and emits fewer greenhouse gases than fossil fuels, it has displaced them. The peak demand of Libya's inadequate public electrical network, which typically happens at midday, is one of the biggest issues. This problem is more prevalent in the summer, when heat waves, higher electrical loads (overload), and decreased energy plant efficiency cause voltage decreases. It is essential to address Libya's high radiation levels around midday in order to solve this issue. It can also be helpful to research and suggest ways to integrate solar energy systems in Libyan residential communities while designing and evaluating the techno-economic implications of doing so. This study assesses the techno-economic viability of the suggested solar system, design a plan for integrating solar energy into Libyan residential areas to support the electrical grid network, and maximize the installation of supported solar systems in residential communities. Both MATLAB/Simulink and HOMER were used in the simulation process. The obtained results demonstrated Libya's residential communities' successful incorporation of solar energy systems. Three electrical loads display net present value, and the work is important for analyzing the discount payback of the three loads. In contrast to low and medium load, big system high load completion is more practical in terms of a fast payback period and will result in a financial cost return in 6.2 years. Therefore, solar energy particularly photovoltaic energy has the potential to be a very practical solution for Libya's power interruptions and oscillations.
