Abstract

A wind energy conversion system (WECS) including a variable wind turbine in grid-connected mode is considered to control. In this paper, each component of WECS model is systematically presented and then the integrated overall model is validated.Regarding to nonlinear nature of WECS and the complex system structure as multiple-input- multiple-output (MIMO),control procedure counters the problem which strategy to handle.To simplify the control policy, a centralized controller which is compatible with systematic modelling introduced, is employed. In other hand to augment the centralized controller performance, an optimization based on genetic algorithm (GA) is accomplished. Simulation results demonstate the proper efficiency in fluctuations mitigation. DOI: http://dx.doi.org/10.11591/telkomnika.v10i4.854

Abstract

In this paper, an improved bacterial foraging algorithm (IBFA) is employed to solve economic-emission dispatch (EED) problem. Regarding to more interest to renewable energy sources especially wind energy in recent years, it is necessary to use of incorporate wind power plants into EED problem. To consider realistic conditions, EED is included bi-objective of cost and NOx emission. The problems encountered with BFA are ineffective bacteria elimination resulted in poor performance. To overcome this, a modified BFA is proposed in reproduction step. EED is performed both with and without wind power plant subjected to couple of constraints using proposed approach and investigated from stand point of cost generation, and grid losses. Simulation results verify the accuracy of the proposed algorithm. DOI: http://dx.doi.org/10.11591/telkomnika.v10i4.851
