Abstract: An arrangement, which is connectable to an alternating current (AC) power transmission system, comprising a static synchronous compensator device having a converter unit and an energy storage unit connected with the converter unit; a power absorption device; and a control device connected with the static synchronous compensator device and with the power absorption device. The control device is configured to control the static synchronous compensator device to exchange power with the AC power transmission system, and to control the power absorption device in dependence of a state of charge of the energy storage unit and a state of the power transmission system. The control device is configured to determine whether there is a need to absorb active power from the AC power transmission system in excess of what the static synchronous compensator device is absorbing and, in case of a need, control the power absorption device to absorb active power.

The MMC is connected in a wye topology with a plurality of converter arms, one for each phase of the AC grid, each arm including a plurality of chain-linked converter cells. The transformer arrangement is arranged to interface each of the arms of the MMC with a respective phase of the grid, and arranged to for each of the converter arms produce leakage reactance resulting in reactance in series with the arm which obviates the need for a phase reactor connected in series with said arm.

Abstract: A system and related methods for volume dimensioning may be implemented by a smartphone, pad, tablet, or similar mobile computing device configured with a three-dimensional imaging system. The system may recognize the edges and corners of an object and infer its dimensions, from which a volume and dimensional weight can be calculated. The system may utilize the determined dimensions to allocate shipping resources to most efficiently and safely transport a shipment through a supply chain, assess damage to an object, assess the compliance of carry-on baggage to size requirements, and quickly assess the stocking of a retailer's and a competitor's products.
