Abstract :
This paper proposes an extended OPF function to efficiently coordinate bilateral contracts with the centralized spot market under a PoolCo environment. The transaction pairs based decomposition is developed to evaluate and compensate parallel flows caused by bilateral trades that involve contract paths. Both transmission loss cost and transmission congestion costs are formulated based upon actual system usage. The presented method is demonstrated to be efficient and accurate through simulated examples
