Special Issue Information

Dear Colleagues,

In recent years, interest in environmental protection and energy sustainability has steadily increased, promoting research activities and projects focused on non-conventional renewable energy (NCRE) sources as a replacement for fossil fuels. In this context, NCRE-based technologies offer a solution for the integration of distributed energy resources; microgrids (MGs) have been introduced to facilitate the integration of many microgenerators, energy storage units and loads. MGs are considered effective solutions for electrification in rural zones, industrial parks, commercial and institutional campuses and other places where distributed renewable resources exist. Moreover, MGs have been explored for other applications, such as in the sectors of agriculture, shipboards and satellites. To ensure the optimal operation of MGs, it is necessary to develop advanced control schemes facilitating the management of these systems.

This Special Issue welcomes original articles on advanced control schemes for managing microgrids and novel and incipient applications where MGs could be used as a novel solution for electric energy generation. We encourage the submission of articles related to but not limited to the following topics to this Special Issue:

  • Planning and operation of microgrids (MGs);
  • Hybrid microgrids AC/DC;
  • Energy–water microgrids;
  • Shipboard microgrids;
  • Agrivoltaics systems;
  • Advanced control strategies for microgrids;
  • Cybersecurity in microgrids;
  • Computational intelligence methods for MGs;
  • Power quality in microgrids;
  • Stability of microgrids.

Modern electrical systems are required to provide increasing standards of power quality, so converters in microgrids need to cooperate to accomplish the requirements efficiently in terms of costs and energy. Currently, power quality compensators (PQCs) are deployed individually, with no capacity to support distant nodes. Motivated by this, this paper proposes a consensus-based scheme, augmented by the conservative power theory (CPT), for controlling clusters of PQCs aiming to improve the imbalance, harmonics and the power factor at multiple nodes of a grid-tied AC microgrid. The CPT calculates the current components that need to be compensated at the point of common coupling (PCC) and local nodes; then, compensations are implemented by using each grid-following converter’s remaining volt-ampere capacity, converting them in PQCs and improving the system’s efficiency. The proposal yields the non-active power balancing among PQCs compounding a cluster. Constraints of cumulative non-active contribution and maximum disposable power are included in each controller. Also, grid-support components are calculated locally based on shared information from the PCC. Extensive simulations show a seamless compensation (even with time delays) of unbalanced and harmonics current (below 20% each) at selected buses, with control convergences of 0.5–1.5 [s] within clusters and 1.0–3.0 [s] for multi-cluster cooperation.

The proposed work delivers a robust control solution for a single-phase permanent magnet synchronous generator-based wind power conversion system (PMSG-WPCS) to enhance grid integration capability. The proposed control approach also offers an extended facility to fulfill low-voltage fault ride-through (LVRT) requirements under adverse grid conditions. Unlike the conventional observer-based PLL (O-PLL) approach, the proposed improved Lyapunov theory-based prefilter (ILP) is helpful in yielding a quadrature signal to solve the single-phase grid synchronization problem. Moreover, the proposed prefilter can leverage delayed signal operation, which improves the harmonic and the DC-offset component rejection abilities while eliminating the need for internal feedback-based submodule blocks for the case of an O-PLL. Consequently, the proposed ILP-PLL exhibits better dynamic behavior to rapidly synchronize a grid-tied power converter and can accurately track the fundamental amplitude information that is required for inverter control to meet the fault ride-through requirements. In addition, the suggested LVRT controller ensures smooth transition between the unity and non-unity power factor modes for superior converter control over reactive current injection into the grid to recover the grid from faults while maintaining a lower amount of total harmonic current distortions. The dynamic performance of the proposed control scheme is experimentally validated in view of the existing O-PLL approach for lower-rating wind-turbine-based PMSG-WPCS. Full article
