Comparative analysis of on-farm timber conversion systems in Kenya
(Journal of Horticulture and Forestry, 2013)Exploitation of trees on private farms in Kenya is mainly by chain, bench and pit sawing systems, whose efficiency has not been well established. The sawing systems were evaluated for their performance using three species: ... -
A GA/IPSO based Approach for System Loss Reduction and Voltage Profile Improvement Employing Arithmetic Crossover and Mutation
(International Journal of Engineering Science and Technology, 2013)Reduction of system losses and improvement of voltage profile is one of the key aspects in power system operation. Though many methods are used to achieve this aspect, Distributed Generation (DG) has found increased usage ... -
Solving The Active Distribution Network Reconfiguration (ADNR) Problem Taking Into Consideration A Stochastic Wind Scenario and Load Uncertainty By Using HBFDE Method
(International Journal of Emerging Technology and Advanced Engineering, 2017)-Past literature has attempted to solve the problem of network reconfiguration with Distributed Generators (DGs) without taking into consideration the intermittent renewable at a close proximity. Distribution ... -
Power Loss Reduction in the Active Distribution Network by Doubly Fed Induction Generator (DFIG) Placement and Sizing Using Ordinary Particle Swarm Optimization (PSO) and an hybrid of Genetic Algorithm (GA) and PSO (HGAPSO)
(2013)Due to the increased importance of DFIGs in optimization of real and reactive power losses and the maintenance of voltage profile, the general methods of DG placement and sizing in the existing literature cannot be ... -
A combined sensitivity factor based GA-IPSO approach for system loss reduction and voltage profile enhancement
(International Journal of Innovative Research in Engineering & Science, 2013)Though several algorithms for optimizing DG location and size in a network with the aim of reducing system power losses and enhancing better voltage profile have already been proposed, they still suffer from several ... -
Combined Real and Reactive Power Economic Dispatch using Multi-Objective Reinforced Learning with Optimized Losses
(International Journal of Scientific and Research Publications, 2015)Most of the economic dispatch (ED) works so far deal with real power dispatch only. With the integration of renewable energy into the grid, reactive power dispatch cannot be ignored any longer due to its importance in ... -
A review of Techniques in Optimal Sizing of Hybrid Renewable Energy Systems
(International Journal of Research in Engineering and Technology, 2015)This paper presents a review of techniques usedin recent published works on optimal sizing of hybrid renewable energy sources. Hybridization of renewable energy sources is an emergent promising trend born out of the need ... -
Effects of Distributed Generation penetration on system power losses and voltage profiles
(International Journal of Scientific and Research Publication, 2013)In present times, the use of DG systems in large amounts in different power distribution systems has become very popular and is growing on with fast speed. Although it is considered that DG reduces losses and improves ... -
Artificial breeding of an optimized solar tunnel dryer using genetic algorithms
(International Journal of Sustainable Energy, 2011)Studies were carried out to artificially breed an optimized solar tunnel dryer using genetic algorithms (GAs). The energy harnessed by the dryer was simulated in Visual Basic Script (Microsoft Visual Basic Script 2010TM) ... -
Voltage Stability Improvement Using the 21st Century Power Transformer
(Innovative Systems Design and Engineering, 2012)The 21st Century Power Transformer is produced by combining modern high voltage cross-linked polyethylene (XLPE) cable technology with conventional transformer. The technique of solid insulation is adopted in the new dry ... -
Optimising Voltage Profile of Distribution Networks with Distributed Generation
(International Journal of Emerging Technology and Advanced Engineering, 2012)Power utility companies are required to supply customers with power within specified voltage limits. Voltage rise in networks with distributed generators therefore poses a challenge. This paper presents a coordinated network ... -
Distributed Slack Bus Model for a Wind-Based Distributed Generation using Combined Participation Factors
(International Journal of Emerging Technology and Advanced Engineering, 2012)With the increased penetration of distributed generation into the power distribution system, the traditional load flow analysis that assumes a single slack bus has become impractical. The existing literature focuses on ... -
