Abstract

Under a deregulated environment, electricity consumers and suppliers generally establish various bilateral power transactions/contracts. The transmission company normally honors and executes these bilateral contracts as far as the system design and operating conditions permit. This paper describes studies of optimal the bilateral contracts by using Line Flow Factors (LFFs). A generalized linear programming formulation is then proposed to solve system operation under a deregulated environment subjected to the steady-state security constraints (e.g. generation and line flow limits). Examples are presented to illustrate how to use this formulation to minimize the cost of any bilateral contract to comply with the security requirements. It was concluded that the proposed methodology will be an effective tool to study the intricate relationships between the bilateral contracts and system security.

 Keywords: generation, load distribution factors and real power transaction.
