Special Issue Information

Dear Colleagues,

We are pleased to invite submissions to this Special Issue of Electronics focused on “Power System Stability and Control”.

With the integration of renewable energy and high-voltage direct current (HVDC) transmission into power systems, the number of power electronic equipment in power systems is quickly increasing. However, due to the complex control, nonlinear switching, and wide-frequency dynamics of power electronic equipment, many new stability issues have emerged, including wide-frequency oscillations and synchronization instability dominated by phase-locked loops. Modern power systems are facing unprecedented challenges in terms of both small-disturbance and transient stability due to the growing structural complexity of grids and heterogeneity of power sources/loads. These issues may cause renewable energy unit disconnection, equipment damage, and even system shutdown. Analyzing and improving the stability of power systems is becoming a key challenge in their planning, operation, and control. Therefore, this Special Issue focuses on the stability analysis and advanced control of power systems dominated by power electronics. Original research articles and reviews are welcome. Topics of interest include (but are not limited to) the following:

  1. The identification and monitoring of instability sources in power systems;
  2. Stability modeling and simulations of power systems dominated by power electronics;
  3. Instability mechanism analysis dominated by renewable energy and HVDC;
  4. Wide-frequency oscillation analysis and mitigation of modern power systems;
  5. Robust stability control strategies for power systems, including model-driven and data-driven approaches;
  6. Application of artificial intelligence in power system stability analysis and control;
  7. Industrial cases and experience.

I look forward to receiving your contributions.

This paper introduces an advanced control method for a Shunt Active Power Filter (SAPF), engineered specifically for the compensation of non-active current and power management in DC-powered systems. Non-active current components frequently arise in practical DC systems due to power electronics and dynamic loads. Their presence leads to increased current draw from the source, higher losses, and accelerated deterioration of DC energy providers, such as fuel cells and batteries. The proposed SAPF control strategy is based on the concept of an equivalent conductance signal, which dynamically reflects the load’s active power consumption and the SAPF’s internal losses. A key feature of this method is the derivation of the conductance signal primarily from the DC-link capacitor voltage, effectively eliminating the need for additional current or power sensors and thereby simplifying the control hardware and software. This methodology enables efficient buffering of energy flow through user-defined time constants, significantly reducing both the average value and the variability range of the current required to transmit the demanded power (as measured by the RMS parameter and standard deviation of the source current, respectively). As a result, the degradation process of energy sources can be mitigated. Furthermore, the conductance signal’s ability to assume negative values allows for effective management of generative loads, enabling power flow back into the system or directing it to specific loads. The flexibility of tuning the SAPF’s functionality—by adjusting the time constant and imposing limits on the conductance signal’s variation range—is demonstrated in the presented results. Simulation examples, including the potential for direct energy exchange with the DC-link capacitor without affecting the upstream source, validate the effectiveness and versatility of the proposed control method in improving power quality and extending the lifespan of DC energy storage systems.
