Abstract:
At present there is an increased focus on using
renewable energy for power generation. In this paper a dispatch
analysis is carried out to identify the effect of increasing variable
renewable energy (VRE) penetration in to the Sri Lankan power
system with the proposed HVDC grid interconnection with India.
Future power system in 2025 was obtained based on least cost
principles using WASP software considering HVDC capacity of
500 MW. The same power system was modeled in the long term
dispatch simulation software, Stochastic Dual Dynamic
Programing (SDDP). High wind and wet periods were considered
due to higher renewable resource availability. Output of SDDP
for each season was input to short term dispatch simulation
software NCP to simulate the daily dispatch along with other
operational constraints and seasonal renewable energy profiles.
When the system cannot meet the specified constraints the
renewable energy curtailments would occur. This process was
carried out to obtain the RE penetration level with 500MW
HVDC for three different scenarios. Scenarios considered for
simulation are aggressive solar, aggressive wind and mix
development of solar and wind. It was observed that with the
proposed HVDC interconnection with India, the renewable
energy level could be increased in the Sri Lankan power system.
