In addition to economic benefits especially in congested areas, the proposed solution can provide back-up for the AC grid and enhance power transmission capacity and flexibility. From the supervisory control point of view, a control algorithm is required to set the reference values for controlling the DC grid power flow based on the desired operating points of meshed AC grid. In this paper, the algebraic model of the DC grid is derived and validated in meshed AC power systems. Algebraic model will present the behavior of AC grid with respect to various operating points of the DC grid, and it is used for steady state analysis. This paper also proposes a droop control structure with dead-band controller for the DC grid. To verify the algebraic model and the control structure, dynamic performance of the embedded multi-terminal DC grid in a reduced order three-bus AC equivalent NYPA power system is investigated in PSCAD/EMTDC environment.}, number={October}, booktitle={IEEE Power and Energy Society General Meeting}, author={Yousefpoor, N. and Parkhideh, B. and Fardanesh, B. and Bhattacharya, Subhashish}, year={2014} }

An efficient approach in reducing the harmonic contents of the inverter's output voltage is total harmonic distortion (THD) minimization. In multilevel inverters with fundamental frequency switching strategy (each switch turning on and off once per output cycle), the switching angles can be selected such that the output THD is minimized. In three phase multilevel inverters, the optimization algorithm is commonly applied to the phase voltage of the inverter. This results in the minimum THD in phase voltage, but not necessarily in the line to line minimum THD. In this paper, THD minimization process is directly applied to the line to line voltage of the inverter, and a new control strategy of multilevel STATCOM is proposed. The proposed method will be implemented, in RTDS and the closed loop operation of multi-level STATCOM will be explored.}, booktitle={2012 IEEE Energy Conversion Congress and Exposition, ECCE 2012}, author={Yousefpoor, N. and Parkhideh, B. and Babaei, S. and Bhattacharya, Subhashish}, year={2012}, pages={1782–1787} }

The AMS is a mobile substation with integrated power electronics and by controlling its throughput power can be connected across different transformers of the grid. The AMS is expected to be at least 20MVA with 230kV and 69kV outputs. This paper proposes transmission-level active mobile substations that provide back-up in case of power transformer failure or forced reduced operation scenarios in addition to power flow control for seasonal renewable energy transmission. These functions altogether have been aggregated not only because of the technical merits but also to address the economic concerns regarding the cost of the power electronics for transmission applications. In this paper, design considerations in development of the AMS will be provided in terms of power electronics building blocks, converter system control and its effects, and required supervisory control.
