    Model Predictive Control-Based AGC for Multi-Terminal HVDC-Connected AC grids
    (IEEE, 2017-04-17)
    McNamara, Paul 
    ;
    Milano, Federico 
    Multi-terminal high-voltage direct current (MTDC) grids are seen as the enabling technology in the development of massive scale international grids such as the European supergrid. It is expected that these grids can play a significant role in regulating ac system frequencies. To date, many proportional-integral (PI) controller-based techniques have been proposed for frequency regulation in ac MTDC-connected grids. In this paper, model predictive control (MPC) is proposed as a means of implementing automatic generation control, while minimizing dc grid power losses. The advantages of using MPC versus PI are highlighted with regard to improvements in both frequency and dc grid regulation, while explicitly considering both delays and dc voltage constraints.

    Efficient implementation of MPC-based AGC for real-world systems with low inertia
    (Elsevier, 2018-05)

    The paper discusses practical implementation and computational aspects of an AGC scheme based on model predictive control (MPC) for a real-world power system, namely the all-island Irish transmission system. This system is particularly interesting from the frequency regulation point of view due to the high penetration of wind power generation. This leads to a significant reduction in system inertia, which in turn impacts on the ability of the system operator to regulate the system frequency. The paper compares the performance of the MPC-based AGC with a conventional AGC based on PI controllers and draws relevant conclusions. The case study is a high-resolution simulation of a 1479-bus model of the Irish electrical grid with significant wind penetration, stochastic loads, and controller delays.

    MPC based AGC for AC/DC grids with delays and voltage constraints
    (IEEE, 2017-07-20)
    McNamara, Paul

    Multi-terminal HVDC (MTDC) grids have been cited as a means of efficiently sharing renewables over wide areas, such as the European grid. As these grids proliferate it is of interest to include these grids in frequency regulation. Here Model Predictive Control is presented as a means of using MTDC grids to aid in Automatic Generation Control (AGC) while considering delays and regulating DC voltages within bounds.
