Energy Management Systems (EMS) for Microgrids
Microgrids are not new to the power systems community, since these local and small grids have been widely deployed and utilized for electricity supply in remote and isolated communities such as islands and remote villages throughout the world. However, there is nowadays a rapid development and deployment of microgrids in the context of smart and resilient power networks, in good part motivated by the integration of distributed generation, especially those powered by renewable resources such as wind and solar, to reduce operational costs and the environmental impact of these grids, particularly for diesel-depended isolated microgrids.
In this talk, an overview of the main characteristics and challenges of EMS for microgrids will be discussed, and EMS architectures associated with deterministic, probabilistic, robust and interval methodologies developed at Waterloo, some of which are being implemented by an industry partner, will be described in some detail. Thus, a two-step EMS approach, which allows to divide the Mixed Integer Nonlinear Programing (MINLP) EMS problem into a simplified Mixed Integer Linear Programing (MILP) unit commitment (UC) problem and a very detailed Nonlinear Programing (NLP) dispatch optimal power flow (OPF) problem, and an EMS integrated architecture, which solves the combined UC+OPF MINLP problem, both based on model predictive control and receding horizon techniques, will be presented. Novel stochastic programing and a robust optimization implementation of the UC problem, to better deal with uncertainty of particularly wind and solar power sources, will be also discussed, together with an interval approach based on Affine Arithmetic (AA) to model and solve uncertain OPF microgrid problems. The practical feasibility and benefits of the proposed EMS approaches will be demonstrated and compared based on results obtained from tests carried out on a realistic benchmark microgrid.

New paradigms in HVDC transmission systems
Continuous increases in electrical energy consumption have encouraged a great deal of technological development in the electrical power industry. In particular, the development of new equipment for power transmission that enables a more flexible power grid aimed at achieving higher throughputs, enhancing system stability and reducing transmission power losses, has been high on the agenda. The VSC-HVDC link is the latest equipment developed in the arena of high-voltage, high-power electronics and its intended function is to transport electrical power in DC form, as well as to enable the asynchronous interconnection of otherwise independent AC systems, and to provide independent reactive power support. The technology employs Insulated Gate BipolarTransistors (IGBTs), driven by pulse width modulation (PWM) control. This valve switching control permits to regulate dynamically, in an independent manner, the reactive power at either terminal of the AC system and the power flow through the DC link. Based on the mentioned above, this conference is focused on the new paradigms of using HVDC transmision systems to face the challenges in the expasion of network infrastructure.
