Special Issue Information

Dear Colleagues,

The technological revolution, introduced with the concept of “Smart Grid”, is changing the structure of traditional transmission and distribution networks. In the upcoming future, the transition from traditional grid to smart grid represents an obligatory step in meeting the new challenges of creating a more efficient and sustainable power supply network. Smart grid has the potential to reduce the carbon footprint by integration of renewable energy sources (RESs), electric active loads, energy storage systems (ESSs), and plug-in hybrid electric vehicles (PHEVs) with the main grid. Power electronics in power systems is mainly used for rectification, inversion, and conversion of electrical power. These electronic devices represent the means to integrate RESs, PHEVs, and ESSs with the main grid. More generally, converters play a fundamental role in the implementation and development of smart grids.

The Special Issue seeks high-quality submissions that highlight emerging converter applications to smart grid; smart control of power electronics to achieve smart voltage and frequency regulation of electric power systems; integration of RES, PHEV, and ESS smart communications with the power grid to sell demand response services; and technological advances in electricity distribution and load management. Topics of interest include, but are not limited to:

  • Smart control applications for renewable energies;
  • Volt/VAR optimization in distribution feeders;
  • Wind turbine (WT) and photovoltaic (PV) applications;
  • Application of power electronics in smart DC and AC distribution systems;
  • Optimal sizing and designing of Hybrid Renewable Energy Systems in smart grid applications;
  • Automation technologies to smooth integration of renewable energy resources;
  • Electric vehicle (EV) propulsion systems and power electronics applications for electrical drives.

This paper introduces a new ellipsoidal-based tracker design to control a grid-connected hybrid direct current/alternating current (DC/AC) microgrid (MG). The proposed controller is robust against both parameters and load variations. The studied hybrid MG is modelled as a nonlinear dynamical system. A linearized model around an operating point is developed. The parameter changes are modelled as norm-bounded uncertainties. We apply the new extended version of the attractive (or invariant) ellipsoid for this tracking problem. Convex optimization is used to obtain the region’s minimal size where the tracking error between the state trajectories and the reference states converges. The sufficient conditions for stability are derived and solved based on linear matrix inequalities (LMIs). The proposed controller’s validity is shown via simulating the hybrid MG with various operational scenarios. In each scenario, the performance of the controller is compared with a recently proposed sliding mode controller. The comparison clearly illustrates the superiority of the developed controller in terms of transient and steady-state responses. Full article
