New Secure Bilateral Transaction Matrix Using AC Distribution Factors with Slack bus contribution and Impact of TCPAR on Its Pattern

In the competitive electricity environment, a large number of transactions are expected to be negotiated, which can compromise the system security and reliability. Therefore, it has become essential to determine secure transactions occurring in the new environment for better planning and management of open access environment. This paper proposes a new method of secure bilateral transaction determination using AC distribution factors with slack bus contribution. The bilateral transaction matrix pattern has been determined in the presence of thyristor controlled phase angle regulator (TCPAR). The optimal location of TCPAR has been determined using mixed integer non-linear programming approach. The bilateral transaction matrix has been determined in a hybrid market model. The proposed technique has been applied on IEEE 24-bus reliability test system (RTS).
