dc.description.abstract | This paper discusses the national drive as well as the drive from the international community to
have sustainable energy as a way to achieve the Sustainable Development Goals. Sustainable
energy requires that more than one energy source is utilized on the grid and these energy sources
have to be renewable. This paper entails how the inclusion of the intermittent renewables impacts
Uganda’s grid stability, particularly voltage stability and frequency stability.
To study the impact of intermittent generation (solar) on the frequency stability of the network,
the swing equation is used. Swing equation is used for modeling the dynamics of the system. It is
then built and simulated using MATLAB. To investigate the impact of intermittent generation on
the voltage stability, the circuit is modelled using Power World Simulator. Cases are then
considered and defined under the contingency scenarios to be considered during the PV analysis.
Voltage stability analysis reveals that increasing intermittent penetration on the network lowers its
voltage stability. The voltage at all the buses reaches the critical point (knee) of the PV curve faster
as the penetration of intermittent power from solar increases thus voltage instability is reached
faster. The Frequency stability of the network is equally lowered by increasing the penetration
level of intermittent generation. At 30% penetration level of intermittent generation, the frequency
of Uganda’s network would become critically unstable.
Adding artificial rotational inertia to Uganda’s network is valuable to increasing the frequency
stability of the network in the face of increasing penetration of intermittent generation. As the share
of intermittent renewables increases on Uganda’s grid, it is recommended that emergency back-up
reactive power reserves and automatic fast start – up of back-up generation are employed to ensure
the maintenance of the voltage stability of the grid. | en_US |
