Coordinated GEP and TEP integrating correlated solar generation and load

Considering the uncertainties associated with the daily profiles of solar power generation and loads, this paper offers modelling to reflect their correlation. Probability distributions are modelled for all uncertain parameters for each hour and respective hourly scenarios are generated by Monte Carlo simulation. These scenarios are then integrated in Coordinated Generation Expansion Planning (GEP) and Transmission Expansion Planning (TEP) framework which offers optimal solution for system expansion. A comparative study reflects the difference in decisions making, with varying load profile.
