It is now more than a decade since distributed generation (DG) began to excite major interest amongst electric power system planners and perators, energy policy makers and regulators as well as developers. This paper presents an overview of the key issues concerning the integration f distributed generation into electric power systems that are of most interest today. The main drivers behind the ...

Power distribution system in the country is characterized by high power losses, poor reliability of supply, frequent equipment burnouts etc. The traditional approach in electric power generation is to have centralized plants distributing electricity through an extensive transmission & distribution network. Distribution generation (dg) provides electric power at a site closer to the customer, el...

As environmental criteria become more and more important for the energy systems operation and planning, this paper proposes a method that can support the decision makers in future electricity systems planning. The evaluation of future electric power transmission investment plans is based on a social welfare analysis when the external costs of production are internalized. The social benefit can ...

This paper addresses issues related to reactive power, voltage support and transmission losses as dictated from a certain class of electric loads. Specifically, it addresses the impact of predominantly induction motor loads on voltage support, reactive power requirements, and transmission losses. These issues are examined with a model, which explicitly models the induction motor mechanical load...

This paper discusses the assessment and visualization of market power in bulk electricity markets, with the explicit consideration of transmission system constraints. In general, market power is the ability of a particular seller or group of sellers to maintain prices profitably above competitive levels for a significant period of time. When an entity has and exercises market power, it ceases t...

This study presents a comprehensive review of the potential technical impacts of plug-in hybrid electric vehicles on power distribution and transmission systems. This review also presents various power quality impacts on the power system in several aspects. This review conveys a detailed analysis of electric vehicle charging strategies on electrical distribution networks. The two charging aspec...

This paper discusses a study of the impacts of ambient temperature gradients along electric power transmission lines on power transfer capability limits. This investigation is performed through the use of novel multi-segment, non-uniform, temperature-dependent line models, which are used to capture the non-uniformity of line parameters caused by ambient temperature variations. For demonstration...

In this paper, we investigate the energy problem of monitoring sensors on high-voltage power transmission lines and propose a wireless charging scheme for a Radio Frequency IDentification (RFID) sensor tag to solve a commercial efficiency problem: the maintenance-caused power outage. Considering the environmental influences on power transmission lines, a self-powered wireless energy relay is de...

This study deals with the control of a hybrid vehicle powertrain, composed of three actuators (one engine, two electric machines). This powertrain belongs to the Electric-Infinitely Variable Transmission (E-IVT) class. In order to achieve low fuel consumption, drivability and electric power management, controllers have to achieve simultaneously three specifications, namely engine speed, wheel-t...
