A New PLL Simulation Validation for Three-phase Grid under Heavy Distorted Conditions

The precision of phase-locked loop (PLL) has a direct effect on the output performance for three-phase grid-connected inverter or three-phase active PFC. In this paper, a new three-phase digital closed-loop phase-locked algorithm is proposed on the basis of synchronous reference frame transformation. Synchronous simulation of the PLL techniques is a good choice even if the polluted three-phase ...

Grid Modification for Second Order Hyperbolic Problems

A family of Galerkin nite element methods is presented to accurately and e ciently solve the wave equation that includes sharp propagating wave fronts. The new methodology involves di erent nite element discretizations at di erent time levels; thus, at any time level, relatively coarse grids can be applied in regions where the solution changes smoothly while ner grids can be employed near wave ...

Passivity-Based Direct power control of Shunt Active Filter under Distorted Grid Voltage Conditions

Despite its many advantages, the conventional direct power control (DPC) of shunt active power filters (SAPF) poses some problems. This paper investigates the design of a new control technical combining DPC control and passivity theory (PT) to ensure quasi-sinusoidal grid currents, under various conditions of the source voltages. The proposed approach (DPC-PT) appeals to the theory of symmetric...

Grid Scheduling Optimization Under Conditions of Uncertainty

One of the biggest challenges in building grid schedulers is how to deal with the uncertainty in what future computational resources will be available. Current techniques for Grid scheduling rarely account for resources whose performance, reliability, and cost vary with time simultaneously. In this paper we address the problem of delivering a deadline based scheduling in a dynamic and uncertain...
