In this paper, a multi-objective reconfiguration problem has been solved simultaneously by a modified ant colony optimization algorithm. Two objective functions, real power loss and energy not supplied index (ENS), were utilized. Multi-objective modified ant colony optimization algorithm has been generated by adding non-dominated sorting technique and changing the pheromone updating rule of ori...

this paper proposes a method to solve multi-objective problems using improved particle swarm optimization. we propose leader particles which guide other particles inside the problem domain. two techniques are suggested for selection and deletion of such particles to improve the optimal solutions. the first one is based on the mean of the m optimal particles and the second one is based on appoin...

This paper presents the optimal scheduling of active distribution network (ADN) with linear and non-linear loads in presence an integrated unit electric spring vehicle parking lot (IUEE). The proposed scheme is formulated form three-objective optimization, which minimizes expected operating cost ADN, voltage deviation function (VDF), total harmonic distortion (THD) separate objective functions....

Abstract With the development of energy Internet, integrated network electricity-gas interconnection has become an important research object optimization. To improve absorption capacity and utilization efficiency renewable in a regional network, comprehensive multi-objective optimization model containing power to gas (P2G) is proposed this paper. The considers two objectives pollutant emission ...

in this paper, simultaneous placement of distributed generation, capacitor bank and protective devices are utilized to improve the efficiency of the distribution network. the objectives of the problem are reduction of active and reactive power losses, improvement of voltage profile and reliability indices and increasing distribution companies’ profit. the combination of firefly algorithm, parti...
