This paper evaluates the renewable energy potential of the Eastern side of the grid of Sumba. In 2018, the renewable energy production in the Eastern Sumba subsystem represents 5.34% of the energy production, and the remaining 94.66% are from diesel engines. It is far from the national renewable energy target of 23% by 2025 and the program of the Sumba Iconic Island. The evaluations pertaining to renewable energy integration should calculate the RES plant’s size and location. A probabilistic approach is adopted to capture the stochastic behaviour of loads and RES generation levels to provide a global view of the impact of RES penetration on the grid. This paper focused on assessing the RES potential integration in Eastern Sumba subsystem using numerical stochastic power flow (SPF) through a series of technical performance indices using power system analysis software. The result of each optimal power flow is recorded, and the process is repeated. The studied system presents long 20 kV distribution lines, thus significant voltage drops. This problem can be solved by adding shunt capacitors or new renewable generators along with installing storages capacities as back up. It has been resulted that PV and WTG in Haharu and PV in Kambajawa (one part of the island) are more reliable to build than PV in Melolo and WTG in Palakahembi (other part of the island), as reflected by active and reactive power losses, voltage deviation and line loading indices.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Line loading,Power-losses,Renewable energies,Voltage deviations,Voltage violation[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]line loading,power losses,renewable energy,voltage deviation,voltage violation[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ISGTEurope.2019.8905645[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
