The main objective of electric power dispatch is to provide electricity to the customers at low cost and high reliability. Transmission line failures constitute a great threat to the electric power system security. We use a Markov decision process (MDP) approach to model the sequential dispatch decision making process where demand level and transmission line availability change from hour to hou...

The future distribution network comprising different energy carriers will include small-scale energy resources (SSERs) and loads, known as a Networked multi-carrier microgrid (NMCMG). This concept not only leads to an efficient reduction in operation costs, but also encompasses the energy transformation between gas and electric networks at combined nodes, as well as district heating networks. I...

In Part I of this work, analysis of uniform multi-conductor transmission line networks is performed on travelling-wave basis, via “quasi-TEM” approach. Narrowband interpretation of the modal theory in the time domain and quantification of the multiple reflections effect are both included. Theoretical demonstration and analytical formulation are provided, along with guidelines towards computatio...

Electric power systems are prominent representatives of the critical infrastructure. Existing electric power systems are composed by two cooperating infrastructures: the electric infrastructure, which is responsible for electricity generation and electricity transmission to customers; and information technology based control systems that monitor and control the physical parameters of the electr...

Open access electric network faces severe congestions due to the increasing demand for power, multiple transactions in the transmission line and outage of network equipment, causing uncertainty and affecting the system security. In this article, different operating states are considered for congestion management in an electric power network. An effective algorithm to reschedule the generating u...

Facing the recent growing concern about the environment and electric power crisis triggered by the Great East Japan Earthquake, efficient use of energy has become an important issue. A smart grid that is a next-generation electric power network is expected to be one of the solutions and to form an enormous market. Aiming to enter this new smart grid market, Sumitomo Electric Industries, Ltd. es...
