| Popis: | In this work, a grid-connected small hydro-solar PV hybrid power system (HPS) was modeled to complement electricity supply in Ado-Ekiti metropolis in Nigeria, and hence, investigated the steady state stability of the distribution networks with and without HPS integration. Consumers’ load audit was carried out through measurement of apparent load at peak periods on each outgoing cable riser from the low voltage circuit of the distribution transformer using clamp-on ammeter which represents loads on respective 11 kV feeders. The solar PV system employed the use of JAP6-72-30/4BB solar PV module and average solar radiation intensity of 4.95 w/m 2 was considered when sizing the solar PV power system. The designed and modeled HPS was integrated into the grid through a hydro inverter and five numbers of parallel-connected 2000 kVA grid-tie solar PV inverters. Simulation analysis of the distribution networks with and without renewable energy integration was carried out using DigSILENT power factory. This work analyzed two scenarios for each of the distribution networks. Simulation results indicated that the networks were stable as evident in the analyses of the renewable grid integration and notable improvement on profile voltage (pu) of all the 11 kV distribution networks were observed. |
