Güç Kaybı ve Arıza Akımı Yönetimi için Dağıtım Şebekesi Yeniden Yapılandırmasının Optimize Edilmesi

Öz

Bu çalışma, ekonomik bir yöntem olan şebeke yeniden yapılandırmasını, arıza akımları ve güç kayıplarının en aza indirilmesi yoluyla güç sistemi performansını optimize etmek için incelemektedir. Gerçekleştirilen tek amaçlı optimizasyon çalışmaları ile hatlardaki ortalama arıza akımının ve güç kayıplarının azaltılması ayrı ayrı hedeflemektedir. Ayrıca, her iki parametreyi aynı anda ele alan bir çok amaçlı optimizasyon çalışması da yürütülmüştür. Optimizasyon senaryoları, 33 baralı test sisteminde Walrus Optimizer algoritması kullanılarak uygulanmıştır. Sonuçlar, yeniden yapılandırmanın, test sisteminin 202.60 kW güç kaybı ve 2.60 p.u. ortalama arıza akımına sahip baz yapılandırmasına kıyasla güç kayıplarını ve arıza akımlarını önemli ölçüde azaltabildiğini göstermektedir. Tek hedefli optimizasyon çalışmaları, güç kayıplarını 139.551 kW'a ve ortalama arıza akımını 2.13 p.u.'ya düşürmüştür. Ayrıca, çok amaçlı optimizasyon çalışması, her iki kriteri de inceleyerek Pareto optimal çözümler aralığı sunmuş ve yeniden yapılandırmanın güç sistemi ihtiyaçlarına uyum sağlama konusundaki esnekliğini vurgulamıştır.

Optimizing Distribution Network Reconfiguration for Power Loss and Fault Current Management

Öz

This study investigates the use of network reconfiguration as a cost-effective method to optimize power system performance through the minimization of fault currents and power losses. In single-objective optimizations, the study targets the reduction of the average fault current of the buses and the power losses individually. Additionally, a multi-objective optimization study is conducted to address both parameters simultaneously. Optimization scenarios are applied on 33-bus test system through Walrus Optimizer. The results demonstrate that reconfiguration can significantly reduce power losses and fault currents, compared to the base configuration of the test system, which had a power loss of 202.60 kW and an average fault current of 2.60 p.u. Single-objective optimizations reduced power losses to 139.551 kW and minimized average fault current to 2.13 p.u. Furthermore, the multi-objective optimization provided a range of Pareto optimal solutions, examining both criteria and highlighting the flexibility of reconfiguration in adapting to power system needs.
