“…State II: The total PV maximum power is less than the sum of the total battery charging power limits and load demands, but is larger than the load demands, as shown in (6). (6) With the condition of (6), all PV units operate at MPP, the batteries absorb the surplus power, and the battery charging power is related to its corresponding SOC and power rating, the load power sharing coefficient λ i is presented as in (7).…”

“…To address the problem aforementioned, the concept of Virtual Synchronous Generator (VSG) is presented, by which, an inverter can be controlled to behave as traditional synchronous generator and provide enough or desired inertia for the power system [6]- [8] so that the dynamic performances of the system can be enhanced. So far, the developments of VSG for microgrids are focused on enhancing system stability [9], [10], distributed control of converters [11] for power system and power sharing in microgrids [12].…”

“…Virtual synchronous control is developed to emulate SGs to embed inertial response in grid-connected voltage source converters (VSCs) [30]- [45] as virtual synchronous generators/machines recently, which has been discussed and studied in energy storage [31], Statcom [32], VSC-HVDC [33]- [36], distributed generation [37]- [39], micro grid [40] used to produce the required voltage, which can feature inertial response in VSCs [43]. In addition, a linear power-damping and synchronizing controller is used to emulate SG's dynamic performance in VSCs by Mohamed et al [44]- [45].…”

Abstract:With the rapid development of wind power generations, the inertial response of wind turbines (WTs) are widely concerned recently, which is important for grid frequency dynamic and stability. This paper recognizes and understands the inertial response of type-3 and type-4 WTs from the view of equivalent internal voltage, in analogy with typical synchronous generators (SGs). Due to the dynamic of the equivalent inertial voltage different from SGs, the electromechanical inertia of WTs is completely hidden. The rapid power control loop and synchronization control loop is the main reasons that the WT's inertial response is disenabled. On the basis of the equivalent internal voltage's dynamic, the existing inertia control method for WTs are reviewed and summarized as three approaches from the view of WT's control, i.e. optimizing the power control or synchronization control or both. At last, the main challenges and issues of these inertia controls are attempted to explain and address.

This paper is focused on the application of a multi-terminal line-commutated converter-type low frequency AC transmission system (MTLF) using a cycloconverter by applying a new power control scheme for multi-terminal operation. With the virtual synchronous generator (VSG) control scheme, the transmitting power among the multi-terminal system can be accomplished without a communication link for frequency synchronization in each terminal. The details of the proposed control scheme are explained in order to understand the advantages of this method. The configuration of a two-phase low frequency AC transmission system (LFAC) is adopted to examine with the proposed control scheme. Simulation results are provided to illustrate the proposed control scheme with respect to the LFAC system's performance.
