Demand Side Management of a grid connected PV-WT-Battery hybrid system

Phiri, S.F.; Kusakana, K. (IEEE Xplore: Industrial and Commercial Use of Energy (ICUE), International Conference, 2016)

Due to technological developments, some isolated areas, where consumers were supplied with electricity using standalone hybrid systems, are currently being connected to the grid. The new problem induced by these ...
Energy flow modeling between grid and micro-hydrokinetic-pumped hydro storage hybrid system

Koko, S.P.; Kusakana, K.; Vermaak, H.J. (IEEE: International Conference on the Industrial and Commercial Use of Energy (ICUE), 2017)

This paper proposes an optimal energy management model for a grid-connected micro-hydrokinetic pumped hydro storage (MHK-PHS) hybrid system supplying the commercial load. The aim of the model is to minimize the energy ...
Flatness based control of a variable speed micro hydrokinetic generation system

Ngancha, P.B.; Kusakana, K.; Markus, E. (International Conference on the Industrial and Commercial Use of Energy (ICUE), 2017)

In this paper, the concept of differential flatness is applied to a controller with the aim of producing constant voltage and frequency from a hydrokinetic with permanent synchronous generator submitted to variable water ...
Grid-interactive micro-hydrokinetic with pumped-hydro storage: The case study of three South African demand sectors

Koko, S.P.; Kusakana, K.; Vermaak, H.J. (IEEE: International Conference on the Domestic Use of Energy (DUE), 2017)

This paper investigates the operation of different demand sector such as residential, commercial and industrial load profiles when supplied with a grid tied micro-hydrokinetic pumped-hydro storage (MHK-PHS) hybrid system. ...
Hydro aeropower, an option for electricity cost reduction in farming applications

Kusakana, K. (IEEE: International Conference on the Industrial and Commercial Use of Energy (ICUE), 2017)

This paper develops a model which can be used to minimize the electricity cost of South African farms through the usage of a wind pump with pico hydro generator and a borehole in pumped hydro storage configuration ...
IMPACT OF DIFFERENT LOAD PROFILES ON SIZING AND PERFORMANCE OF A MICRO-HYDROKINETIC-BATTERY BASED HYBRID SYSTEM

Koko, S.P.; Kusakana, K.; Vermaak, H.J. (Stellenbosch: Conference: Proceedings of the 25th Southern African Universities Power Engineering Conference, 2017)

Hydrokinetic hybrid systems are gaining more interest since hydrokinetic technology has proved to offer a cost-effective electrification solution. Very few research studies on sizing and optimization of micro-hydrokinetic-battery ...
Modelling and simulation of a power converter for variable speed hydrokinetic systems

Ngancha, P.B.; Kusakana, K.; Markus, E. (International Conference on the Domestic Use of Energy (DUE), 2017)

This study presents the control scheme model of a micro-hydrokinetic turbine system equipped with a permanent magnet synchronous generator (PMSG). A power conversion system model is developed to allow a variable speed ...
Optimal scheduling of a grid-connected hydrokinetic-battery system under Time of Use tariff

Kusakana, K. (IEEE Xplore: Domestic Use of Energy (DUE), 2016 International Conference, 2016)

In this work, the optimal power scheduling for a grid-connected hydrokinetic-battery hybrid system is proposed to sufficiently explore hidrokinetic energy and to benefit customers at demand side. The developed model ...
Optimized scheduling of diesel - renewable systems with pumped hydro storage

Bokabo, B.; Kusakana, K. (IEEE Xplore: Industrial and Commercial Use of Energy (ICUE), 2016 International Conference, )

The present paper develops a model to optimize the daily operation of a hybrid energy system consisting of a photovoltaic unit, a wind unit, a pumped hydro storage system and a diesel generator. The main purpose of the ...
A review of solar photovoltaic systems cooling technologies

Siecker, J.; Kusakana, K.; Numbi, B.P. (Renewable and Sustainable Energy Reviews, 2017)

Cooling the operating surface is a key operational factor to take into consideration to achieve higher efficiency when operating solar photovoltaic systems. Proper cooling can improve the electrical efficiency, and ...
Solar Thermal Organic Rankine Cycle (STORC) power plant as an alternative to the steam power plant with a parabolic trough system in South Africa

Odufuwa, O.Y.; Kusakana, K. (IEEE: International Conference on the Domestic Use of Energy (DUE), 2017)

This paper analyses the possibilities of incorporating the Organic Rankine Cycle (ORC) technology to a parabolic trough technology, reduces the cost of testing and optimisation by providing tools for the evaluation and ...
A survey of differential flatness-based control applied to renewable energy sources

Ngancha, P.B.; Kusakana, K.; Markus, E. (IEEE PES PowerAfrica, 2017)

This paper presents an overview of various methods used to minimize the fluctuating impacts of power generated from renewable energy sources. Several sources are considered in the study (biomass, wind, solar, hydro and ...
A SURVEY OF DOMESTIC WATER HEATING TECHNOLOGIES

Hohne, P.A.; Kusakana, K. (Conference: Proceedings of the 25th Southern African Universities Power Engineering Conference, At Stellenbosch, 2017)

In South Africa, heating water for domestic use is one of the most energy consuming processes in residential buildings. This process represents up to 60% of the total energy in the residential sector. Using more efficient ...
Techno-economic analysis of multiple paralleled diesel generators for micro isolated applications

Kusakana, K. (IEEE: International Conference on the Domestic Use of Energy (DUE), 2017)

This paper analyses the key benefits of a multiple paralleled diesel generator system over a "Single" diesel generator system for supplying small remote and isolated loads. Even though having several small diesel ...
