The major goal of this paper is to study the problem of power dispatch for bilateral contract. The proposed problem was separated into two parts in this thesis. The first deals with the deregulated electricity market, where Generation Company and Distribution Company will be permitted to establish bilateral service contracts in the market. The Independent System Operator (ISO) has an overall responsibility to execute these bilateral contracts as far as the operating conditions permit. In this thesis, the problem of power dispatch for bilateral contract is formulated as minimization of deviations from transaction requests made by market participants. In addition, various constraints consisting of capacity coupling, spinning reserve capacity and transmission line constraints are explicitly taken into account. We also consider the impact of transmission congestion and environmental constraints. DC load flow and interior point (IP) methods were used in solving this problem. According to various simulations, the proposed method is reliable and helpful for ISO¡¦s power dispatch.
Second part of the thesis deals with the flexible AC transmission system (FACTS) devices, such as thyristor controlled series compensators and thyristor controlled phase shifters, under transmission congestion. Evolutionary Programming, known to avoid local convergence and achieve nearly global optimum, was used to solve this combinatorial optimization problem. FACTS installation tried to solve or improve congestion in the transmission network for bilateral contracts. It could also provide planning tools for system expansion for operators¡¦ references.
