in restructured power systems and in a wholesale power market, a distribution company as a market player intends to maximize its profit by utilizing its options. hence determining an optimal energy acquisition strategy for a distribution company is vital, for attaining to this goal. however an important challenge for determining these strategies is forecasting other competitors and generation c...

It has long been argued that developing distributed software is a difficult and error-prone activity. Based on previous work on design patterns and skeletons, this paper proposes a template-based approach for the high-level design and implementation of Distributed Virtual Environments (DVEs). It describes a methodology and its associated tool which includes a user-interface, a performance analy...

The presence of distributed generation (DG) provides considerable benefits from both engineering and economic viewpoints. However, it changes radial configuration of the distribution feeders. Consequently it may cause coordination failure to existing protection system which is originally set based on radial configuration. In addition, high penetration level of DG may increase feeder loss, and c...

Distributed generation (DG) is rapidly increasing its penetration level in Australia, and is expected to play a more important role in the power industry. An important benefit of DG is its ability to defer transmission investments. In this paper, a simulation model is implemented to conduct quantitative analysis on the effect of DG on transmission investment deferral. The transmission expansion...

This paper presents simulation results for a taxonomy of typical distribution feeders with various levels of photovoltaic (PV) penetration. For each of the 16 feeders simulated, the maximum PV penetration that did not result in steady-state voltage or current violation is presented for several PV location scenarios: clustered near the feeder source, clustered near the midpoint of the feeder, cl...

In this paper, a novel framework is proposed to study impacts of regulatory incentive on distributed generation (DG) investment in sub-transmission substations, as well as upgrading of upstream transmission substations. Both conventional and wind power technologies are considered here. Investment incentives are fuel cost, firm contracts, capacity payment and investment subsidy relating to wind ...

The battery energy storage systems (BESS) have been gaining notoriety in recent years due to the high penetration of renewable energies distributed generation. It has main goal providing a dispatchable and reliable generation source. This study details implementation BESS with bidirectional converter as interface between bank supply network. converter’s modeling control equations are presented,...
