In deregulated power systems, the distribution network operator (DNO) is not responsible for investment in Distributed Generation (DG) units and they are just concerned about the best architecture ensuring a good service quality to their customers. The investment and operating decisions related to DG units are then taken by entities other than DNO which are(More)
This paper presents the application of Information Gap Decision Theory (IGDT) to help the Distribution Network Operators (DNOs) in choosing the supplying resources for meeting the demand of their customers. The three main energy resources are pool market, Distributed Generations (DGs) and the bilateral contracts. In deregulated environment, the DNO is faced(More)
This paper presents a dynamic multi-objective model for distribution network expansion, considering the distributed generations as non-wire solutions. The proposed model simultaneously optimizes two objectives namely, total costs and technical constraint satisfaction by finding the optimal schemes of sizing, placement and specially the dynamics (i.e.,(More)
This paper proposes a hybrid possibilistic-probabilistic evaluation tool for analyzing the effect of uncertain power production of distributed generations (DG) on active losses of distribution networks. The considered DG technologies are Gas and wind turbines. This tool is useful for Distribution Network Operators (DNOs) when they are faced with(More)

In this article, a new approach for power system dynamic stability assessment has been presented. The proposed approach is based on standard Fuzzy ARTMAP discussed in our previous paper [1] and its modified version called PROBART (Probability ART). Besides Fuzzy ARTMAP, Neural architecture with probability Fuzzy ARTMAP is considered as a modified Fuzzy(More)
We propose novel techniques to find the optimal location, size, and power factor of distributed generation (DG) to achieve the maximum loss reduction for distribution networks. Determining the optimal DG location and size is achieved simultaneously using the energy loss curves technique for a pre-selected power factor that gives the best DG operation. Based(More)
In this article, two different types of neural network architectures namely multilayer perceptron and Fuzzy ARTMAP neural network are compared in an application to a power system problem. In order to evaluate the ability of these two neural networks, the power system dynamic stability problem has been considered and the performance and deterioration of the(More)
