Transmission price simulator in a liberalized electricity market

This paper presents a software tool (SIMCMTP) that solves congestion situations and evaluates the taxes to be paid to the transmission system by market agents. SIMCMTP provides users with a set of alternative methods for cost allocation and enables the definition of specific rules, according to each market and/or situation needs. With these characteristics, SIMCMTP can be used as an operation aid for Transmission System Operator (TSO) or Independent System Operator (ISO). Due to its openness, it can also be used as a decision-making support tool for evaluating different options of market rules in competitive market environment, guarantying the economic sustainability of the transmission system.
