“…An ongoing trend in these projects is being the increase of voltage levels of the converters, aiming medium voltage distribution grids. An early prototype of a series active power filter for distribution systems in 13.8kV has been developed by their researchers in [7] however a step-up transformer (with 220:13800 ratio) had been used and this had resulted in elevated currents at the low voltage side. Recently, the Institute has also partnered in the project of a peak-shaving equipment with energy storage on batteries, also for distribution systems in 13.8kV [8] -still using a coupling transformer -however, using a multilevel topology (Cascaded H Bridge) on the converter, which resulted in a smaller transformer ratio (2400:13800) and decreased the current rating on the semiconductors.…”

This paper presents the detailed project of a modular educational kit to be used in research and teaching activities in the area of power electronics -with emphasis on applications in medium voltage multilevel converters. The half bridge topology has been chosen for the submodules, as they can be arranged together in a multitude of other topologies. A system composed by a mother board and daughter cards is presented. A DSP control card and a FPGA System-On-Module are inserted in the mother board in order to control the half bridge submodules. The targets of this project are applications in medium voltage -hence, the communication between the submodules and the FPGA/DSP is performed through optical fibers. Also a self power system is presented for the submodules, in order for them to operate at floating potentials. Experimental results have been presented for the most usual topologies of converters, including a Modular Multilevel Converter operating at 2000V.

“…The greatest challenge concerning the 13.8kV operation is the blocking voltage capability of the semiconductors used in the electronic converter. In [19], the authors have used a distribution transformer to increase the voltage capability of a series active power filter. However, the higher the transform ratio, the higher will be the current ratings at the low voltage side.…”

This paper presents the development and operation on 13.8kV distribution systems of a peak-shaving equipment with battery energy storage. This equipment injects active power to grid during peak times (when the cost of energy is higher) and charges its battery banks from the grid at the off-peak times (when the energy has a low producing cost). The equipment is based on a multilevel converter coupled to the grid through a 2.4kV:13.8kV transformer. In addition to the peak-shaving functionality, a feature of compensation of harmonics on the distribution voltage is included, without the need for any extra sensor nor hardware (apart from the ones already in use for the peak-shaving). The compensation of voltage harmonics is performed through the emulation of a harmonic resistance in order to damp resonances between system impedances that are excited by non-linear loads. This approach is very appealing to distribution systems, where the non-linear loads are not accessible and are scattered. Experimental results obtained on a 13.8kV test substation are presented.
