Power system operation became a challenging with the integration of variable and uncertain Renewable Energy Sources (RES) generation. The operational flexibility describes the technical ability of the power system to respond to the net-load within a controllable power at a certain time to accommodate the RES power output. The main objective of this paper is to analyse and evaluate the impact of the...
This paper empirically studies the performance of the particle swarm optimization (PSO) technique. A practical test system in power system studies is selected as a testing function. The test system takes into account the valve-point effects. The study aims to tune four main parameters involved in the PSO implementation in a typical economic load dispatch problem. The experimental results illustrate...
The gravitational search algorithm (GSA) has been used in this research to optimize output of the multiple distributed generator (DG) units in autonomous distribution network. With the optimal operation of DGs, the voltage profile can be improved, thus reducing the power losses in the system. The performance of GSA is compared with an established paper, which uses the genetic algorithm (GA) in analysing...
