Abstract: Utility restructuring, technology evolution, an expanding power market, and environmental policies are compelling a fast growth of distributed energy resource (DER) in many countries in recent years. With some salient advantages, DERs are playing an increasingly vital role in the restructuring environment and benefit many stakeholders: the utility, independent power producers, and electricity consumers.As DERs have an escalating economic impact on the power system, the conventional utility cost minimization algorithms developed for the non-DER environment should be modified to take into account the involvement of DERs. This research aims to meet this challenge: two enhanced overall cost minimization approaches for the hybrid generation environment, the Iteration Approach and the DER Integration Approach, are developed in this thesis. These two approaches, along with a conventional non-DER approach, have been applied on a test system. Comparisons of these resulting minimum generation costs confirm the positive economical impact of DERs on the system.
