Received Oct 14,2012 Revised Jan 05, 2013 Accepted March 02,2013 In practical cases, the fuel cost of generators can be represented as a quadratic function of real power generation and satisfied constraints for minimizing of fuel cost. Artificial bee colony (ABC) algorithm is used for the optimization of active power dispatch of generating units. The proposed method is able to determine, the ou...

The Economic Load Dispatch (ELD) problem is how to real power output of each controlled generating unit in an area is selected to meet a given load and to minimize the total operating cost in the area. This is one of the important problems in a power system. The Hopfield Neural Network (HNN) has a good capability to solve optimization problems. Recently, the economic load dispatch problem solve...

The optimized dispatch of different distributed generations (DGs) in stand-alone microgrid (MG) is of great significance to the operation’s reliability and economy, especially for energy crisis and environmental pollution. Based on controllable load (CL) and combined cooling-heating-power (CCHP) model of micro-gas turbine (MT), a multi-objective optimization model with relevant constraints to o...

One of the primary goals of distributed systems is effective coordinated use of their resources. In a distributed system, an imbalance load distribution on its nodes may reduce the performance of the overall system. Load balancing is a strategy to allocate arriving tasks to the proper nodes to improve the overall performance of the system. This paper introduces a classification for load balanci...

Original scientific paper Economic Load Dispatch problem has been previously solved successfully with swarm techniques. However, power systems with complex behaviours still await a robust algorithm to be developed for their optimization more precisely. Economic Dispatch problem with constraints such as generator limits, total power demand, ramp rate limits and prohibited operating zones, makes ...

2 I. INTRODUCTION Power system economics procedure includes of two aspects: active power regulation and reactive power dispatch. This forms a global optimization problem of a large-scale industrial system.The reactive power problem is less manageable to solve than the active power problem due to its more complicated relationship between variables. The reactive power problem is largelyassociated...

Differential Evolution (DE) algorithm is a heuristic approach for minimizing nonlinear and non-differentiable continuous space functions (storn, 1997). However, the implementation of DE requires some estimate of the global minimum to be provided, which is difficult for any arbitrary function. Also, the termination with maximum number of iterations does not assure the global minima. Moreover, as...

Recently, the expansion of energy communities has been aided by lowering cost storage technologies and appearance mechanisms for exchanging that is driven economics. An amalgamation different renewable sources, including solar, wind, geothermal, tidal, etc., necessary to offer sustainable smart cities. Furthermore, considering induction large-scale electric vehicles connected regional micro-gri...
