How can power generation and distribution systems be made more efficient?5 answersPower generation and distribution systems can be made more efficient through the implementation of distributed generation (DG) technologies. DG involves bringing generation sources closer to the load centers, which improves the reliability and reduces the power losses in the distribution system. The optimal location for DG units can be determined using computational techniques such as artificial neural networks (ANN). The integration of renewable energy systems into the network through DGs can help address the limitations of centralized production, such as the lack of fossil fuels and the need to reduce pollution. Power quality issues in distribution systems can be improved by ensuring proper implementation of electronic power converters and addressing switching frequency challenges. Analytical and optimization techniques like Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) can be used to determine the best sizing and placement of DGs in the electric grid, leading to reduced power losses and improved voltage stability. Solutions for mitigating the negative impact of DG on power supply systems, such as changes in emergency currents and overvoltage, can be achieved through alternative protection systems and algorithms.
How can smart grid technology be implemented in distribution systems?4 answersSmart grid technology can be implemented in distribution systems through various approaches. One approach is the integration of smart grid technologies in distribution systems, particularly behind-the-meter initiatives, which has a direct impact on transmission network planning. Another approach involves drawing up the structure of a distribution smart grid and dimensioning it based on criteria such as minimum discounted costs, minimum power loss, or minimum amount of undelivered electricity. Additionally, the implementation of smart grids requires the integration of advanced sensors, a two-way communication infrastructure, and high-performance computation-based control in distribution management systems. Furthermore, the digital transformation of distribution networks into smart grids involves the introduction of Intelligent Electronic Devices (IEDs) and the use of suitably arranged laboratories for research, development, and testing activities. These approaches aim to improve the quality of service, enhance customer orientation, and accommodate the increasing presence of distributed energy sources in distribution networks.
