Abstract:
To be able to reduce CO2 emission and move towards eco-friendly energy, the planet
is moving towards alternative energy sources. The aims that will undoubtedly enhance
the percentage of alternative energy inside the electrical grid include the use of
distributed generation (DG), such as rooftop solar panels (PV) and wind turbines.
According to the International Renewable Energy Agency, the number of nations that
have chosen a goal to incorporate alternative energy on their electrical grid has
increased from 43 to 168 in only 10 short years. These goals call for the use of
Distributed Generation (DG), such as rooftop PV System, or the development of
modest, distributed renewable energy facilities, such as wind farms and PV farms. The
purpose of this study is to examine how the grid is affected by high PV and wind
penetration. For the Western System Coordinating Council's distribution network, a
detailed study of the test system supplied by the WSCC 3 Machines, 9 Bus Test Case
(P.M. Anderson 9 Bus) using Etap software 19.01 produces a fairly crude
approximation model to an analogous system with 9 buses and 3 generators. [1]-[3].
Six scenarios were taken into consideration, two types of tests were conducted to look
into load flow analysis, transient stability analysis, and harmonic analysis were
performed individually for each degree of transmission, and to simulate the effects of
DG (Solar and Wind) plant penetration over time, three degrees of integration were
considered. Furthermore, to be able to check out the grid performance during extreme
climate conditions, scenarios were modeled to find the intermittent qualities of
alternative energy generation. The acquired results demonstrated excellent
performance from the grid for transmission under 40% while greater degree of wind
and solar transmission takes some work and adjustment on the grid side.
