Economic load dispatch is conducted by the utilities in order to determine the best generation level at the most feasible operating cost. In order to guarantee satisfying energy delivery to the consumer, a precise calculation of generation level is required. In order to achieve accurate and practical solution, several considerations such as prohibited operating zones, valve-point effect and ramp-rate...
This paper presents the implementation of Modified Swarm Firefly Algorithm (MSFA) technique which considers the effect of population size in solving directional overcurrent relay coordination problem. The coordination of directional overcurrent relays is formulated as linear programming problem and the proposed technique is compared with those obtained using Particle Swarm Optimization (PSO). Implementation...
In energy industry, generating the correct amount of electrical power is crucial. Economic load dispatch is used to compute the necessary amount of power among the generators. However, each generator in a system is limited by its physical properties that will limit its maximum potential. This prohibited zone divides the actual operation limits of a particular generator into several subdivisions. This...
Emission dispatch deals with the process of determining the emission level produced by thermal power plants. Since the concerns toward environmental health paramount, emission dispatch has become a crucial consideration during energy dispatch planning. Different fuel types produce different types of pollutant and thus the total emission level may vary. However, the fluctuation of future load demand...
Emission dispatch is a topic that discusses on the discharge of polluting substance by fossil-fuelled generators. The arising concerns towards environmental quality arouse new trend in power flow studies. Emission dispatch has become a vital consideration during load dispatch scheduling and the power utilities are urged to reduce the pollutant volume to the least. Numerous approaches have been employed...
Unit commitment is among of the key elements in power system planning. Unit commitment is extensively applied by the power utilities to plan the optimal dispatch of generating units in the system. In the deregulated power system industry, it is important to consider several uncertainty constraints during the planning process. This research proposes the application of fuzzy set modeling to determine...
This study was conducted in order to classify and then to identify the different types of PD based on the characteristic of the harmonic orders. The data from the experimental work has been validated before the harmonic analysis can be commenced. Once the validation stage has been completed, the obtained data is then analysed in terms of its fundamental power frequency and the characteristic associated...
