Development of an effective restoration scheme for a Ugandan power system using hydro, thermal and co-generation

Power system restoration continues to be a major challenge for many power systems in sub-Saharan Africa. Hydropower generation also remains as one of the major sources of power in this region. However, many power systems supported by hydropower generation in this region suffer from frequent power system blackouts, which have detrimental implications on the power system and its users. This paper focuses on systematic restoration strategies and studies of blackouts to aid the development of an effective restoration scheme for a Ugandan power system using the available hydro, thermal and cogeneration. This scheme is required to operate for different blackout scenarios that have been imposed on the power system, using hydro, thermal and co-generation. Two blackout scenarios were imposed on the Ugandan test system to initiate the design of the scheme. The testing of the proposed scheme and validation of its effectiveness are done on DIgSILENT PowerFactory 15.2 through simulations of the case studies.
