MY LATEST RESEARCH

Conventional power system studies are normally performed using offline analytical tools and computer simulations. Hardware-in-the-loop (HiL) configurations are very helpful to carry out experimental tests in a safe environment without affecting the operation of a practical power system. Following this line, a real-time HiL (RT-HiL) platform suitable for a wide range of power system studies is presented in this paper. Emphasis is placed on the individual components of
the hybrid hardware-based emulator in HiL configuration. To demonstrate the capabilities of the RT-HiL configuration, two case studies are presented: subsynchronous resonance damping and fast frequency support provision. The ac grids are modeled in the RT simulator, while dc networks are implemented in a physical test-bed. The ability of the RT-HiL platform to emulate ac/dc interactions and grid support services is shown. For completeness, experimental results are compared against PSCAD simulation results—showing a good agreement.

Power system interconnections using high-voltage direct-current (HVDC) technologies between different areas can be an effective solution to enhance system efficiency and reliability. Particularly, the multi-terminal dc grids that could balance and ensure resource adequacy increase asset utilization and reduce costs. In this paper, the technical feasibility of building dc grids using the line-commutated converter-based (LCC) and voltage source converter-based (VSC) HVDC technologies is discussed. Apart from presenting the technical challenges of building LCC dc grids and LCC/VSC hybrid dc grids, the reliability modeling and analysis of these grids are also presented.

Angle-DC is a smart and flexible method for reinforcing distribution networks. The project is creating a controllable bidirectional Direct Current (DC) link between two sections of our network, Isle of Anglesey and North Wales. Angle-DC is converting existing 33kV Alternating Current (AC) assets to DC.

Power flow control in multi-terminal HVdc (MTdc) grids is essential to restrict operation within permissible limits. A current flow controller (CFC) can achieve this. In this paper, the modeling, control, and simulation of resistive, RC-circuit based and capacitive CFCs are carried out. CFC prototypes have been developed and an MTdc grid test-rig has been employed for experimental validation. 

Asset Management Strategies for Power Electronic Converters in Transmission Networks:

this paper reviews the state-of-the-art of asset management strategies in the power industry and indicates the research challenges associated with the management of high power converter assets. Emphasis is made on the following aspects: condition monitoring, maintenance policies, and ageing and failure mechanisms.
