Asynchronous interconnection of the Proposed East Africa power pool (EAPP)

Musau, Peter M.; Odero, Nicodemus A.; Wekesa, Cyrus W. (IEEE, 2017-06-27)

East Africa Power Pool (EAPP) is a proposed regional interconnection for centralizing energy resources and facilitating power wheeling between the Eastern Africa geographical areas. Synchronous tie lines have been used in ...
Effects of renewable energy on frequency stability: A proposed case study of the Kenyan grid

Musau, Peter M.; Chepkania, Terry L.; Odero, Abungu N. (IEEE PES PowerAfrica, 2017-06-27)

Renewable Energy (RE) units especially grid connected Wind and Solar PV which have no rotational inertia are effectively displacing the conventional generators and their rotating systems. This reduces both the cost of ...
Comparative analysis of implementation of solar PV systems using the advanced SPECA modelling tool and HOMER Software: Kenyan scenario

Kibaara, Samuel K.; Murage, D. K.; Musau, Peter M.; Saulo, M. J. (Ital Publication, 2020-03-01)

Globally, attention has been focused on the pollution and exhaustion of fossil fuels allied to conventional energy sources, while non-conventional energy/renewable energy sources have always been considered clean and ...
Effect of Streamflow on Hydro-Power Generation in the Upper Tana River Basin, Kenya

Musyoka, Francis K.; Wambua, Raphael M.; Mutua, Benedict M. (2018-06)

Hydro-power is one of the Kenya’s important energy sources. The main hydro-power project in Kenya is located in the Upper Tana River basin. There has been a fluctuation of power generation due to climate change over the ...
Evaluation of streamflow response to agricultural water abstraction and its variability with rainfall for Thiba river watershed, Kenya

Omondi, Brian; Mutua, Benedict M.; Wambua, Raphael M. (2018-06)

The continuous increase of agricultural water demand in Thiba River Watershed as a result of the expansion agriculture especially in the Mwea Irrigation Scheme and other parts of the watershed has led to over abstraction ...
Drought forecasting under climate change scenarios using artificial neural networks for sustainable water resources management in upper Tana River basin, Kenya

Mutua, Benedict M.; Wambua, Raphael M.; Raude, James M. (PAUWES Research-2-Practice Forum, 2018-07)

Climate change has continued to impact negatively on water resources globally. For instance, extreme weather conditions especially the drought phenomena have become frequent in Africa. This has prompted water engineers and ...
Flood frequency analysis towards food security in upper Njoro river catchment, Kenya

Amisi, Leah; Kundu, Peter M.; Wambua, Raphael M. (2019-06-13)

Upper Njoro River catchment (UNRiC) falls within the Eastern Mau forest situated along the western escarpment of the Rift Valley. It serves as the head water for Njoro River which is the major river draining its water in ...
Prediction of infiltration rate in different land use types using modified Horton equations in upper Njoro river catchment

Amisi, L.; Wambua, Raphael M.; Kundu, P. M. (2020-01-21)

Infiltration rate is a fundamental parameter in understanding a wide range of soil functions. The determination of the infiltration rate in the field usually requires a lot of time. Horton's equation is a viable option ...
A modified approach for monitoring technical and non-technical losses in a distribution feeder in a developing country: the democratic republic of Congo as a case study

Muzalia, Kikuni B.; Moises, Peter M. (IEEE, 2022)
