Mitigating Power Loss in Distributed Generation Using Water Cycle Algorithm and Capacitor Banks

Problem Definition

The current state of modern distribution systems reveals a pressing issue of escalating demand for high-quality power, accompanied by the challenge of effectively mitigating power losses within the network. Existing compensation instruments and loss computation mechanisms are inefficient, preventing the successful reduction of power losses. Despite various proposed techniques such as Demand Side Management (DSM), capacitor placement, and Distributed Generators (DGs), accurate loss computation at individual network entities remains a significant obstacle. This limitation hinders the optimization of power flow and distribution, resulting in operational inefficiencies and increased costs. Therefore, the development of innovative solutions that enable precise loss computation for each network entity is essential to implement effective power loss reduction techniques and enhance overall system performance.

Objective

The objective is to develop innovative solutions that enable precise loss computation for each network entity in modern distribution systems, in order to implement effective power loss reduction techniques and enhance overall system performance. This will be achieved by utilizing the Water Cycle Algorithm (WCA) to minimize power losses, improve distribution efficiency, optimize power flow, enhance voltage profiles, improve system stability, minimize operational costs, and consider environmental factors like emission reduction. By integrating D-FACTS instruments such as DSTATCOMs, capacitor banks, and distributed generation units, the performance and power quality of distribution systems can be enhanced. The goal is to provide a flexible and cost-effective solution for improving distribution system performance by achieving more efficient results compared to traditional random methods.

Proposed Work

In modern distribution systems, the demand for high-quality power is escalating rapidly, making it crucial to effectively mitigate power losses within the network. Despite existing techniques like Demand Side Management and capacitor placement, accurate loss computation at individual network entities remains a challenge, hindering optimization efforts and increasing operational costs. To address this gap, the Water Cycle Algorithm (WCA) is proposed for minimizing power losses and improving distribution efficiency. By integrating D-FACTS instruments like DSTATCOMs, capacitor banks, and distributed generation units into distribution systems, the performance and power quality can be enhanced. The WCA algorithm aims to optimize power flow by reducing distribution losses, improving voltage profiles, enhancing system stability, and minimizing operational costs while also considering environmental factors like emission reduction.

By introducing a chaos-based initial population strategy, the algorithm can achieve more efficient and optimal results compared to traditional random methods, providing a flexible and cost-effective solution for improving distribution system performance. Taking the trending progress in the power electronic instruments in mind, D-FACTS, in particular DSTATCOMs are implemented in 2 distribution networks for enhancing the quality power and fulfilling the needs of reactive power for reducing losses in power and upgrading the level of voltages. Integration of capacitor banks (CBs) and distributed generation units (DGs) in DS endeavor to augment the performance of the system. The hybrid penetration of DGs and CBs can reduce distribution power losses, improve voltage profile and therefore enhance the overall distribution system performance and also leads to cost-efficient system. However, these approaches do not enhance the all technical, environmental as well as economic issues of DS and also do not provide flexible operation and thus the optimal results are not achieved.

Also, in the existing approaches, the initial population is generated on a random basis which is time-consuming and also the optimal results were not obtained in enhancing efficiency. To resolve the previous issues and to obtain efficient results, the water cycle algorithm (WCA) is utilized, which is a new meta-heuristic algorithm. The WCA algorithm aims to optimize power flow by reducing distribution losses, improving voltage profiles, enhancing system stability, and minimizing operational costs while also considering environmental factors like emission reduction. By introducing a chaos-based initial population strategy, the algorithm can achieve more efficient and optimal results compared to traditional random methods, providing a flexible and cost-effective solution for improving distribution system performance.
