Abstract

There is a need to develop an optimization tool that can be applied in the feasibility study of a hybrid renewable energy system to find the optimal capacity of different renewable energy resources and support the decision makers in their performance investigation. A multi-objective function which minimizes the Levelized Cost of Energy (LCOE) and Loss of Load Probability Index (LLPI) but maximizes the novel Energy Match Ratio (EMR) was formulated. Simulation-based optimization method combined with ε-constraint technique was developed to solve the multi-objective optimization problem. In the study, ten-year hourly electrical load demand, using the end-use model, is estimated for the communities. The performance of the developed algorithm was evaluated and validated using Hybrid Optimization Model for Electric Renewables (HOMER®) optimization software. The developed algorithm minimized the LCOE by 6.27% and LLPI by 167% when compared with the values of LCOE ($0.444/kWh) and LLPI (0.000880) obtained from the HOMER® optimization tool. Also, the LCOE with the proposed approach was calculated at $0.417/kWh, which is lower than the $0.444/kWh obtained from HOMER®. From environmental perspective, it is found that while 141,370.66 kg of CO2 is saved in the base year, 183,206.51 kg of CO2 is saved in the ninth year.The study concluded that the approach is computationally efficient and performed better than HOMER® for this particular problem.The proposed approach could be adopted for carrying out feasibility studies and design of HRES for Off-Grid electrification, especially in the rural areas where access to the grid electricity is limited

Abstract

Water is essential for human life and activities, but its supply depends on the proximity and interconnection network with the populations or cities that need it. Moreso, the proper functioning of water supply systems (WSS) relies on the expertise and experience of field workers who rely on information from maps or field surveys, whose processes and mapping methods are labour-intensive, time-consuming, and are done relatively infrequently. This study explores modern spatial databases for meaningful technical progress using the Quantum Geographic information system (QGIS) server to host a web-based geocoding platform to view the production, transmission, and delivery of drinking water from the source to household users according to the capacities planned for by WSS. The resultant results met expert expectations on the designed web system and showed information on pipe network, road connection, drinking water distribution layout, catchment boundary, slope, and sub-catchment geometric properties demonstrating the utility of a web-based online Map plugin in the GIS environment as a data management, scenario analysis, and decision support tool in managing water infrastructure for an expanding metropolitan city like Ilorin, Kwara State.
