Study of Assessing the Stability of Rwanda’s Power System from Big Data Based on Power Generation

Rwanda has insufficient of electricity in which the electricity access among its citizens is at 53% equals to 224 MW of power generation. However, even among 53% of electrification, there are still some blackouts and erratic outages in cities during the night when many devices are connected on the system. This blackout and sudden shutdown could make the power system stability of Rwanda to be questionable and it can be so-called unstable. Meanwhile, the Rwanda Government is very ambitious targeting to achieve universal access by 2023/24 in which 52% will be on-grid connected and 48% off-grid. In this study, the current and proposed Rwanda power generation sector, transmission sector, and distribution sector are discussed; general Rwanda energy sources like, hydro, solar, diesel thermal, methane gas, peat are also discussed based on big data. In the end, conclusion and some recommendations have been proposed to be done in order to make stable the power system. For instance, Kalman-filtered solar forecasting approach could be used to predict weather condition every hour so that blackout coming from bad atmosphere could be prevented.
