초록/요약
Because of the growing environmental concerns, national energy companies and Utilities are increasingly adopting renewable energy technologies in an effort to reduce thermal and nuclear plants and their implications to the environment. But as more renewable energy increases into the system, the role of power systems and utilities becomes even more complex. So, when planning and deciding the optimal strategy to ensure that the role of power systems is achieved, a generation system expansion plan is necessary taking into account all the technical, economic and environmental constraints. Generation expansion planning aims to capture some of the complex challenges of variable RE integration for more appropriate energy polices. Construction of power plants requires immense financial and time investment therefore generation system expansion planning has to evaluate the cost over the specified period of planning. Therefore, the aim of this study is to determine the optimal generation expansion plan that will facilitate the right renewable energy capacity addition and expansion that will satisfy Uganda’s growing energy needs while meeting its climate change goals too. The study also aims at determining the economic impact of increasing large amounts of variable renewable energy into the generation expansion plan of Uganda. The study compared two scenarios, scenario A and Scenario B. Scenario A is one without solar PV integration and scenario B is one with solar PV integration in the generation expansion plan. The goal of the study was to compare the two scenarios to determine the least cost generation expansion option between the two alternatives and the economic effect of large-scale solar PV integration.
