Estimation of Rwanda's Power System Inertia as Input for Long-term Dynamic Frequency Response Regulation Planning

Changes in the quota between conventional generation and renewable energy sources constitute major challenges that modern power systems have to encounter. Conventional plants are replaced by (e.g. wind turbines, photovoltaics) contribute reduction of system inertia. This may introduce frequency stability issues because is affected amount inertia, along with response controllable reserves imbalance. Therefore, estimation analysis inertia assessment essential ensure security. paper proposes a novel method estimates constant for three different periods future, namely, 2025, 2035 2050 based on produced future scenarios (FES) Rwandan's system. In addition, evaluates dynamics each scenario. Results show highest progression resources penetration resulted larger (from 7.2 control area 1 3.83s 3) largest drop was observed during high scenario year where PV imported expected reach more than 30% total installed capacity.
