Copula based self scheduling model for risk averse GenCo in restructured electricity market

One of the important task of risk management process is the scenario consideration by knowing the dependence structure between market uncertainties. The paper presents a new copula based self scheduling (CB-SS) model for generation companies (GenCos) in day-ahead Indian electricity market (EM). Energy prices and unscheduled interchange (UI) charges are taken as market uncertainties. The proposed model also takes into account the forced outages of GenCo units as operational uncertainty. The uncorrelated uncertainty sources are modeled using copula to capture the dependence structure. Conditional value at risk (CVaR) is used as a risk measuring technique. The proposed model is tested on a GenCo situated in northern region of Indian EM.
