Active filter solutions in energy systems

A Review on Energy Storage Systems Planning in Active Distribution Networks and its Applications

With the restructuring of power systems, increase of renewable energy sources, and as networks become smarter, power systems are facing new challenges such as uncertainty in available energy resources. An appropriate solution to address these challenges are to use energy storage systems. Therefore, sizing, location, and selection of energy storage systems are important to maximize their benefit...

Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

Pseudo energy wells in active systems

Active stabilization in systems with zero or negative stiffness is an essential element of a wide variety of biological processes. We study a prototypical example of this phenomenon at a microscale and show how active rigidity, interpreted as a formation of a pseudo-well in the effective energy landscape, can be generated in an overdamped ratchet-type stochastic system. We link the transition f...

Active Motion in Systems with Energy Supply

Biological motion, human traffic and many other types of active motion rely on the supply of energy. In order to derive a rather general approach for active motion, we have proposed a model of active Brownian particles, which have the ability to take up energy from their environment, to store it in an internal energy depot and to convert internal energy to perform different activities, such as ...

Active Filter Energy Storage Requirements for Non-periodic Current Compensation

This paper presents a discussion of the compensation of non-periodic currents such as those associated with arc furnaces. Based on the compensation objectives for different types of load waveforms, the energy storage requirements of the compensator are also presented. Further, basic concepts required in the definition of nonactive current are presented and illustrated by simulations for a varie...
