Abstract :
The installation of solar PV systems in
distribution networks is slowly increasing. The study
focused on identifying the challenges and benefits of
installing Distributed Solar Generation in the Chipata
33kV and 11kV distribution Networks. Chipata Town is in
the Eastern Part of Zambia, and it has a peak demand of
about 23.3MW. The 2023 version Power Factory Dig
Silent Software was used to model the Chipata 33kV and
11kV distribution network and different Solar penetration
levels were used to understand the impact of Distributed
Solar. Chipata Distribution Network has four major
stations operating at 33kV and 11kV voltages and four
main distribution lines. The main objective of the study
was to determine the impact of distributed solar PV in the
Chipata Distribution Network. One of the specific
objectives was to determine the hosting capacity of the
Chipata Distribution Network. The hosting capacity gives
the maximum amount of PV power integrated in a power
system network without violating the set operation limits.
The study analysed the impact of solar Distributed
Generation on network losses, fault levels, voltage stability
and line loading. The study revealed that an increase in
penetration level resulted in a general increase in the Bus
Bar voltages on both 11kV and 33kV voltage levels.
Different Penetration levels of solar ranging from
6.66MW to 132MW were studied. Simulations revealed
that the hosting capacity for Chipata Distribution
Network is 96MW (412% of Solar PV Penetration Level).
The voltages in the distribution network at hosting
capacity were ranged from 0.93p.u to 1.02p.u. Short
Circuit analysis simulations showed negligible impact on
the fault level after integration of solar in the distribution
network. Some circuits showed both increased and
reduced power losses with increased solar penetration.
The obtained results indicated that increased installation
of distributed Solar PV systems in the Distribution
Network impacts voltage stability, line losses and line
loading.
