International Journal of Engineering Research & Technology, 10(03), 366-370p-2278-0181https://repository.futo.edu.ng/handle/20.500.14562/2826This article contain figuresThe work covers transient configuration of the grid connected photovoltaic-diesel power production in multiEngineering building complex of Federal University of Technology, Owerri (FUTO), Nigeria. The electric power shortage in Nigeria and the global drive towards exploring new energy sources have facilitated the consideration of the grid connected photovoltaic-diesel power generation, as a viable solution to poor energy supply system in multi-Engineering complex of FUTO, Nigeria. The work is achieved through estimation of complex’s daily average load profile in a consecutive number of ten hours, complex`s component selection and sizing of solar panels and solar PV modules, inverter without battery storage capacity, diesel generator capacity, transient configuration and modeling using Matlab/Simulink Sim scape Tool. The same tool is deployed for the transient configuration simulation of the developed system. The performance evaluation of the simulation results revealed that the active and reactive powers recorded permissible elongated transient duration period ranging from 0 to 3 seconds when the diesel generator is supplying the set load alone. However, when PV and diesel generator are connected to the building complex load without the grid, the transient optimum operation ranging from 0 to 2 seconds is recorded. The estimated load for the complex is approximated as 150kW, and this load operates at an average duration of 10 hours daily to produce approximately a total daily energy for the complex as 2,000KWh per day throughout the lifetime of the system design, which is shared among the PV-diesel power plant configuration at the ratio of 60%:40% daily. The PV system would supply 60% of the total daily power and energy demand of 89.616kW and 1,176.384KWh per day whereas, the diesel generator supplies 40% of the total daily power and energy demand of 59.744kW and 784.256KWh per day, so as to reduce the daily cost of fuel consumption.enAttribution-NonCommercial-ShareAlike 4.0 InternationalMatlab/simulink simscape toolPV energy source and diesel generatorinverter without battery storage capacitytotal daily power and energy demandDepartment of Electrical Electronic EngineeringFUTO Multi-Engineering Building ComplexArticle
