A Review of Multi-objective Particle Swarm Optimization Algorithms in Power System Economic Dispatch
Particle swarm optimization (PSO) has received increasing attention in solving multi-objective economic dispatch (ED) problems in power systems because of parallel computation, faster convergence, and easier implementation. This paper presents a detailed overview of multi-objective particle swarm optimization (MOPSO) and provides a comprehensive survey on its applications in power system econom...
For the application of large-scale mobile agents in a distributed environment, where a large number of computers are connected together to enable the large-scale sharing of data and computing resources, security and efficiency are of great concern. In this paper, we present secure route structures and corresponding protocols for mobile agents dispatched in binary to protect the dispatch route i...
Background: Considering the increased frequency of high-risk pregnancies that require further care, most high-risk mothers are dispatched from medical centers to higher-level hospitals. Therefore, the present study aimed to determine the frequency and causes of dispatching high-risk pregnant mothers from the medical centers to the delivery department of Yazd Shahid Sadoughi Hospital in 2011 - 2...
Multiple dispatch allows determining the actual method to be executed, depending on the dynamic types of its arguments. Although some programming languages provide multiple dispatch, most widespread object-oriented languages lack this feature. Therefore, different implementation techniques are commonly used to obtain multiple dispatch in these languages. We evaluate the existing approaches, pre...
The rational economic load dispatch can not only save the energy, but also improve efficiency of power systems. Therefore it is important to research economic load dispatch problem. However, The problem is a complex and nonlinear optimization problem considering valve-point loading effects of generating units; it is difficult to solve the problem using traditional optimization method. Therefore...
The task of efficient vehicles dispatching in real time becomes very important for service and transportation companies. In general, dispatch management requires complex perceptual and cognitive abilities applied under a high level of stress; the development of a knowledgebased expert system for dispatch management reduces both stress and risk in decision-making and increases economic efficienc...
Economic dispatch problem is an optimization problem where objective function is highly non linear, non-convex, non-differentiable and may have multiple local minima. Therefore, classical optimization methods may not converge or get trapped to any local minima. This paper presents a comparative study of four different evolutionary algorithms i.e. genetic algorithm, bacteria foraging optimizatio...
The Combined Heat and Power Economic Emission Load Dispatch (CHPEED) is an optimization problem to minimize the cost and emission while ensuring the fulfilling the power and heat demand and feasible constraints. This paper presents Particle Swarm Optimization (PSO) technique and other to solve CHPEED with bounded feasible operating region. The main potential of this technique is that it proper ...
Abstract: Microgrid is one of the newest technologies in power systems. Microgrid can usually has a set of distributed energy resources that makes it able to operate separate from power grid. Optimal operation of microgrids means the optimal dispatch of power resources through day and night hours. This thesis proposed a new method for optimal operation of microgrid. In this method, real-time pr...
This paper proposes a simple and efficient approach for the optimal dispatch in a medium-voltage microgrid (MG) with various types of distributed generation (DG). The fuel costs generated by these DGs are determined using quadratic and linear functions dependent on the types of DGs. Instead of using the traditional Lagrange multiplier method for power system economic dispatch, the proposed dire...
