The successful integration of intermittent and distributed electric generation from renewable resources can be viewed as a coordination problem at multiple scales in both space and time. This paper presents an overview of coordination issues relative to the goals for renewable integration in California.
We propose two optimization-based models for computing the allowable penetration level of multiple distributed generators, taking into account voltage regulation constraints. A single level optimization model is developed for computing the maximum penetration level, while a bi-level optimization model is developed to answer the question as to at least how much power a distribution system can accommodate...
In this paper a control strategy based on predictive control ideas is proposed for reconfiguring on-line the on-load tap changer (OLTC) voltage set-point in electrical medium voltage (MV) power grids in the presence of distributed generation (DG). The idea is that an active management of the set-point can be effective for maintaining relevant system variables within prescribed operative constraints...
The increasing connection of distributed energy generation in a distribution network may lead to unacceptable voltage rise. An automatic voltage reference setting technique, acting on the tap change control of the transformer supplying the network, can be used to address this problem. By measuring essential voltage points along the distribution network, an automatic voltage reference setting technique...
This paper discusses the application of a shunt active power filter with energy storage, for voltage and power improvements within a local power supply network (micro-grid) in presence of distributed generation. Theoretical analysis investigates the control the shunt active power filter in response to voltage sag. The shunt active filter operates over a short period of time, and is coordinated with...
