24-Hours Load Forecasting Using a Hybrid of Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) for Optimized Neural Network
TabanInyasioSiriOgugu, Stephen; Abungu, N.O; Wekesa, Cyrus Wabuge (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 ... -
Modelling Simulation and Optimal Sizing of a Hybrid Wind, Solar PV Power System in Northern Kenya
Okinda, Victor; Abungu, N.O (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 ... -
Optimal Under - frequency Load Shedding using Cuckoo Search with Levy Flight Algorithm for Frequency Stability Improvement
Mwaniki, C; Muriithi, C M.; Abungu, N.O; Nyakoe, G N. (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
Mwaniki, C; Muriithi, C M.; Abungu, N.O; Nyakoe, G N. (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
Musau, Peter Musau; Abungu, N.O; Mbuthia, J.M (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 ...
