This paper presents the concept of the generalized power source in an active distribution network. After the energy storage system (ESS), distributed generators (DG), and demand-side controllable load are connected to the active distribution network, part of the system load can be undertaken by these ESS, DG, and controllable load instead of relying on the capacity of the substation, which grea...

Active Networking is an innovative technology which can open the network and make it more flexible. But, introducing active code within the network increases the network vulnerability from security point of view. The security is always considered as a separated component or an upper layer of the active network architecture. In this paper, we develop a global security architecture for a safe cod...

the enzyme rhodanese (thiosulfate: cyanide sulfurtransferase) is a ubiquitous enzyme and its activity ispresent in all living organisms. many functions including cyanide detoxification, formation of iron-sulfurcenters and participation in energy metabolism have been attributed to this enzyme. the enzyme catalyzesthe transfer of a sulfur atom from sulfane containing compounds (such as thiosulfat...

We previously demonstrated a high speed, point to point, quantum key distribution (QKD) system with polarization coding over a fiber link, in which the resulting cryptographic keys were used for one-time pad encryption of real time video signals. In this work, we extend the technology to a three-node active QKD network one Alice and two Bobs. A QKD network allows multiple users to generate and ...

This paper concerns sensor network key distribution schemes (KDS) based on symmetric-key techniques. We analyze the problem of active attacks against such schemes. By active attacks we mean those attacks, where the adversary can maliciously disturb the communication between the sensors. We observe that the active adversary that captured even a small number of sensors, can anyway get a full cont...

This paper designs a reliability distribution network with limited capacity under partial and complete facility disruptions. To increase the reliability of the distribution network, a new mixed integer linear programing model is developed by considering multiple mitigation strategies including diversification, fortification, and transshipment. The distribution network constitutes of reliable di...

The concept of an active network has been mentioned recently to adapt to the large-scale implementation of distributed generation. Distributed State Estimation is one of the most important functions to enable this novel concept. This paper proposes a completely decentralized state estimation (CDSE) method suitable for the active network. CDSE is based on multi-agent system technology to compute...

The traffic light concept of the German Association of Energy and Water (BDEW) to coordinate and market power in the distribution system level defines different mechanisms to ensure network stability in dependence of the criticality of the system state. But what is a critical network condition and how is it possible to detect a critical network condition timely, effective, and possibly also at ...
