Abstract :

This paper presents a comprehensive solution for optimizing the performance of distributed generation units in distribution systems. Focusing on reducing distribution network losses, the proposed solution utilizes point-to-point pricing method to determine prices across the distribution system. The optimization objective is to minimize network losses, utilizing participatory prices declared by the owners of distributed generation units. Furthermore, price optimization is carried out using an improved grey wolf optimization algorithm, which employs a decision tree model to identify optimal solutions in each iteration, enhancing speed and accuracy at each stage of the algorithm training. The efficacy of the proposed method is evaluated on two IEEE 33-bus and 69-bus test distribution systems in MATLAB software, showing significant improvement in the speed and accuracy of the proposed solution compared to previous methods. Overall, this study can contribute to the advancement of efficient strategies for managing distributed generation units in distribution systems, emphasizing profitability and addressing network optimization challenges.
