The power flow management scheme for a microgrid (MG)‐connected system utilizing a hybrid technique is suggested in this dissertation. An MG‐connected system includes photovoltaic, wind turbine, micro turbine and battery storage. Due to the use of this resource, power production is intermittent and unpredictable, as well as unstable, which causes fluctuation of power in hybrid renewable energy system...
Economic Load Dispatch (ELD) is an important problem in power system optimization. It helps to create very efficient unit management plans and keeps the generation cost to a minimum. In this paper, we have addressed ELD problem with a novel improved algorithm called Elitist Cuckoo Search (ECS) keeping in mind the practical constraints of a plant such as generation ramp rate and prohibited zones of...
This paper focuses on unit sizing of stand-alone hybrid energy system using Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) and comparative performance study of these two meta-heuristic techniques on hybrid energy system. The hybrid system is designed focusing on the viability and combining different renewable energy sources like wind turbines, solar panels along with micro-hydro plant...
This paper presents a new adaptive differential evolution technique based on logistic map for optimal distribution placement and sizing. The parameters of differential evolution that need to be selected by the user are the key factors for successful operation DE. Choosing suitable values of parameters are difficult for DE, which is usually a problem-dependent task. Unfortunately, there is no fix rule...
This paper presents a cultural algorithm based technique to achieve the optimal size and placement of Static Var Compensators (SVCs) in a power system. A multiobjective reactive power problem is chosen here to establish the feasibility of the algorithm. Two objective functions are proposed for reducing the SVC investment cost while minimizing the active power loss but maintaining voltage stability...
Cultural algorithm is a well suited optimization technique for several multiobjective optimization problems. In this paper this cultural approach is used to solve reactive power planning problem considering the real power losses and the deviation of a given voltage schedule combining as a multi-objective model. Var control method is the key of optimal reactive power flow problem. In this paper the...
In general power system problems like reactive power dispatch (RPD) are nonlinear, non-differentiable and multi-constrained based. This type of problem is solved by various analytical programming and meta-heuristics algorithms. Among the different applied techniques, metaheuristics algorithms have always maintained themselves competitive with analytical programming. Simulated annealing (SA) is one...
