Advanced DMS to manage active distribution networks

2009 IEEE Bucharest PowerTech, 2009
The paper presents an advanced Distribution Management System capable to manage an active distribution network economically and safely. The DMS optimizes the power flows in the network, regulates the voltage profiles, acting on reactive flows and tap changers in substation, minimizes the energy losses, reconfigures the network, exploits storage devices

Activity Based Matching in Distributed Camera Networks

IEEE Transactions on Image Processing, 2010
In this paper, we consider the problem of finding correspondences between distributed cameras that have partially overlapping field of views. When multiple cameras with adaptable orientations and zooms are deployed, as in many wide area surveillance applications, identifying correspondence between different activities becomes a fundamental issue.

Dynamic Behavior of Active Distribution Networks

2021 56th International Universities Power Engineering Conference (UPEC), 2021
Due to the increasing penetration of renewable energy sources, which are mainly connected to the distribution grid level, the active and reactive power flows in the distribution grids become more volatile. To avoid costly grid expansions Distribution System Operator uses voltage controlling components, such as on-load tap changing transformers or ...

ACDN: Active Content Distribution Network

2005
A novel dynamic and active CDN architecture based on active network (ACDN) is proposed. The programmable character of active network makes it easier and quicker to configure new replica servers as well as deploy new policies on demand. A genetic algorithm (GA) based replica server placement optimization algorithm is designed and implemented, as well as

Robust distribution state estimation for active networks

2008 43rd International Universities Power Engineering Conference, 2008
A heuristic optimization algorithm based on the Dynamic Programming theory is proposed to find the optimal placement of measurement devices, i.e. to determine their number and position. The optimization procedure explicitly considers network reconfigurations (caused by random faults or by the active management of the network), so that the final ...

Active distribution network concept for distributed management of low voltage network

IEEE PES ISGT Europe 2013, 2013
The paper proposes a concept and architecture for distributed low voltage network management. Active distribution network concept is capable of real-time monitoring of whole grid and it may utilize the flexibility of distributed energy resources to enhance the hosting capacity of low voltage networks.

Distributed state estimation technique for active distribution networks

2007 42nd International Universities Power Engineering Conference, 2007
The need for higher frequency in state estimation execution covering larger supervised networks has led to the investigation of faster and numerically more stable state estimation algorithms. However, technical developments in distributed energy management systems based on fast data communication networks open up the possibility of parallel or ...

Optimal operation of active distribution networks with Distributed Energy Storage

2012 IEEE International Energy Conference and Exhibition (ENERGYCON), 2012
The main goal of active distribution network operation is the minimization of system cost given by the sum of the costs of energy losses, curtailed energy, reactive support, shed energy, and storage operation. The paper focuses on the use of Distributed Energy Storage, showing that suitable OPF algorithms embedded in the Distribution Management System ...

Normally Distributed Activity Durations in PERT Networks

Journal of the Operational Research Society, 1985
It is assumed that activity durations in a PERT network are independent and normal random variables. A recurrence method of determining the lower and upper bounds on the mean event occurrence time is presented. In comparison with previous methods, the proposed procedure is considerably simpler, while on the other hand the errors of approximations are ...

A distributed-active bandpass network configuration

Proceedings of the IEEE, 1971
A new distributed-active circuit, which has lower sensitivities and which utilizes its capacitor area more effectively than the circuit described in an earlier correspondence, is described.
