Abstract
The quest for economic growth has led to increase in world's energy consumption and to meet this continuously widening energy gap, high penetration of variable energy resources (VER) into the energy mix of countries all over the world is being encouraged. However, there is a limitation on the capacity of existing transmission facilities and the power system is more susceptible to voltage instability issues and the number of outages caused by voltage collapse has increased greatly. In this paper, a capacity factor based approach for optimal penetration of utility-scale PV solar power into the Nigerian power system considering voltage stability is discussed and compared with the line loss minimization approach. Multi-objective particle swarm optimization algorithm on MATLAB® is used to compute sufficient capacity of solar PV that the power system can accommodate while maintaining the stability of the system. An additional constraint based on voltage stability margin is included to keep the system within the stability margin. The proposed approach with the added constraint is found to perform better for both line loss reduction and voltage stability improvement than the line loss minimization approach. Two optimization algorithms are used to verify the accuracy of the approach for techno-economic planning.
