Probabilistic security-constrained preventive redispatching in presence of correlated uncertainties

This paper proposes a probabilistic algorithm of preventive redispatching for conventional generators aimed at ensuring N-1 security in the presence of correlated uncertainties of renewables and loads.

The strong penetration of renewables, characterized by related forecast uncertainties, requires adequate tools to help electricity system operators manage security. This paper proposes a probabilistic algorithm for preventive redispatching for conventional generators aimed at ensuring N-1 security in the presence of correlated uncertainties of renewables and loads. The algorithm combines the third-order polynomial normal transformation, the Point Estimate Method, and the Cornish Fisher expansion to characterize probability constraints in a linear programming-based optimization problem. Simulations performed on an IEEE test network demonstrate the effectiveness of the proposed security control method in limiting the probability of violating transit boundaries on branches in state N and N-1.
