24-Hours Load Forecasting Using a Hybrid of Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) for Optimized Neural Network
(International Journal of Emerging Technology and Advanced Engineering, 2016)Short-term load forecasting (STLF) has emerged as one of the most important fields of study for efficient and reliable operation of power system. It plays a very significant role in the field of load flow analysis, contingency ... -
The Dependency of Bus Voltage and Frequency in Load Shedding
(2014)Load shedding schemes proposed in literature so far use voltage and frequency parameters separately. The individual consideration of these indices may not be reliable or effective, and may even lead to the over load ... -
An Efficient Method of Load Forecasting for Non-Working Days
(2012)A new efficient method is proposed to forecast the non-working days load demand at Ruiru substation which is a 66/11kv; 66/33kv distribution substation located along Thika road. The forecasts are based on the total daily ... -
An experimental Prototype for Low Head Small Hydro Power Generation Using Hydram
(2012)The global rise in energy demand has resulted to the over exploitation of both renewable and non renewable energy sources. Most feasible hydroelectric power (HEP) plants sites have been exploited and the current focus is ... -
Modelling Simulation and Optimal Sizing of a Hybrid Wind, Solar PV Power System in Northern Kenya
(ational Journal of Renewable Energy Research, 2016)Solar and wind, the most abundant renewable energy resources are still expensive to deploy and are unreliable as they are intermittent. It has long been postulated in open published literature that solar and wind have ... -
Multi Objective Dynamic Economic Dispatch with Renewable Energy and HVDC Transmission Lines
(2016)HVDC systems have recently found increasing importance in integration of Renewable energy (RE) into the grid for they provide long distance bulk power transmission by overhead lines with various economic advantages. The ... -
Optimal Under - frequency Load Shedding using Cuckoo Search with Levy Flight Algorithm for Frequency Stability Improvement
(International Journal of Emerging Technology and Advanced Engineering, 2015)Frequency stability in a power system is very important as it determines the synchronous speed of electrical machines. Therefore it should remain within acceptable limits even when the system is disturbed. In order to ... -
Optimal Under - voltage Load Shedding using Cuckoo Search with Levy Flight Algorithm for Voltage Stability Improvement
(International Journal of Engineering Science Invention, 2015)Voltage stability has become a serious threat of modern power system operation nowadays. To tackle this problem properly, load shedding is a countermeasure taken as a last resort. However, its consequences might result in ... -
Reducing Real and Reactive Power Losses in the Power Distribution System by DFIG Placement and Sizing Using Ordinary PSO and HGAPSO
(International Journal of Emerging Technology and Advanced Engineering, 2012)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 ... -
Short Term Load Forecasting Using Artificial Neural Network
(Institute of Electrical and Electronics Engineers, 2007)This paper presents a method of short term load forecasting using artificial neural network (ANN). A three layered feed-forward neural network, trained by scaled conjugate back-propagation, is used. Two models of ANN were ... -
Simultaneous Consideration of Bus Voltage and Frequency in Load Shedding in a High Voltage AC Network
(2015)Load shedding schemes proposed in literature so far use voltage and frequency parameters separately. The individual consideration of these indices may not be reliable or effective, and may even lead to the over load ... -
Solution to Economic Load Dispatch using Particle Swarm Optimization
(2014)This paper proposes to determine the feasible optimal solution of the economic load dispatch power systems problem using Particle Swarm Optimization (PSO) considering various generator constraints. The objective of the ... -
Stability Analysis of a Multi Area System with Renewable Energy and Multi -Terminal DC Tie Lines
(Journal of Power and Energy Engineering, 2018)Security constrained multi area multi objective dynamic economic dispatch (SCMAMODED) with renewable energy (RE) and all the possible MTDC stability constraints is formulated for the first time. The stability merits of ...
