Computation of Locational Marginal Pricing in the Presence of Uncertainty of Solar Generation

In an integrated power system with solar generation, congestion in transmission lines and its management is a pivotal task. To deal and manage the congestion, one can adopt technical or commercial aspect. Computation of Locational Marginal Pricing (LMP) gives commercial perspective and can be commercial solution for congestion management. This work presents a strategy for assessment of LMP in the presence of solar generation in a restructured power system. To analyze the effect of uncertainty on marginal pricing, IEEE 30-bus framework is thought of. Real time based solar insolation from 1stJanuary 2014 to 31st December 2018 data points are investigated, the distribution followed by data is normal. Equivalent generator output values, over a period of 4 years are considered. The data is actual historical records obtained from IMD department, Pune district, India.
