Abstract

The optimal allocation of protective devices is a serious issue in an electrical power system; in order to reduce the possibility of faults, the protection devices should be optimally placed. The paper presents a continuous genetic algorithm (CGA) for the optimal allocation of directional relays for the efficient energy minimization in a radial distribution system (DG). The algorithm is flexible to use for the changes and improvements in the optimal location for a DG unit and can optimize the energy consumption in the radial distribution system. The proposed algorithm has been implemented on IEEE 33 and 69-bus system using MATLAB (R2014b, MathWorks). Low energy consumption is a common design objective in an energy-constrained distribution system. Engineers, power utilities, and network operators can profit from the proposed methodology to enhance the use of DG in distribution networks. [ABSTRACT FROM AUTHOR]

Abstract

This paper presents an application of heuristic optimization techniques such as Harmony Search Algorithm (HSA), Particle Swarm Optimization (PSO), and Genetic Algorithms (GA) for efficient operation in micro grid. For operational efficiency, the objective function in a diesel generator consists of the fuel cost function similar to the cost functions used for the conventional fossil-fuel generating plants. The wind turbine generator is modeled by the characteristics of variable output. The operating cost in fuel-cell system includes the fuel costs and the efficiency for fuel to generate electric power. The application of the heuristic optimization technique to optimal operation can save the operating costs of the distributed generation and interruption costs in micro grid. The method proposed is applied to the IEEE 13-buses system to compare its solution. [ABSTRACT FROM PUBLISHER]
