Special Issue Information

Dear Colleagues,

Achieving fully sustainable energy requires integrating large amounts of renewable energy into modern grids. Different from fossil fuel energy, which is applied to synchronous generators (SGs), renewable energy resources, like wind and solar energy, are commonly connected to the grid through inverters. It is envisioned that SGs will gradually be replaced by inverter-based generators as the penetration of renewable energy continues to grow. Meanwhile, as flexible regulation resources for the grid, the applications of inverter-based resources (IBRs) on both energy storage systems and vehicle-to-grid-enabled electric vehicles have developed tremendously. However, the penetration of ubiquitous IBRs can greatly complicate the dynamic properties and challenge the indispensable real-time source-load energy balance of power systems. To this end, this Special Issue will focus on advanced technologies for operating IBR-rich renewable energy power systems (REPSs).

Topics of interest include, but are not limited to, the following:

Topic 1: Stability analyses and control methods for IBR-rich REPSs;

Topic 2: Resilience-oriented coordinated energy management of IBR-rich REPSs;

Topic 3. Flexible resource aggregation for accommodating increasing IBR-based renewables;

Topic 4: Advanced artificial intelligence (AI) applications for operating IBR-rich REPSs;

Topic 5: Emerging system services and market designs for IBR-rich REPSs.

To address the challenge of a conventional line-commutated converter (LCC), unable to operate properly in connection with a very weak AC system, the technology of the capacitor-commutated converter (CCC) was widely utilized in 1990s. The topology of the CCC is constructed as a conventional LCC modified with a series capacitor between the converter transformer and the thyristor valves in each phase. Additional phase voltage can be generated on the capacitor to assist the process of the commutation. However, the CCC technology may experience continuous commutation failure due to the uncontrolled charging of the series capacitor. Based on the submodule-cascaded static synchronous compensator (STATCOM), this paper proposes a novel topology called the submodule-cascaded STATCOM-based CCC (SCCC). The SCCC technology enables the function of reactive power compensation and active filtering. It can also improve the transient characteristics of the AC faults via dynamic reactive power injection during the transient process, which helps to reduce the risk of continuous commutation failure in the CCC.

The series-connected DRU-MMC hybrid converter, with its compact size and cost-effectiveness, presents an attractive solution for long-distance offshore wind power transmission. However, its application is limited by the DRU’s unidirectional power flow and the voltage mismatch between the auxiliary MMC and the onshore MMC during black-start operations. To overcome these challenges, a four-stage black-start strategy utilizing an auxiliary step-down transformer connected to the onshore MMC is proposed. The proposed strategy operates as follows: The onshore MMC first lowers its valve-side voltage via an auxiliary transformer, enabling reduced DC-side voltage. With the DRU bypassed, the offshore MMC draws startup power through the DC link, then switches to V/f mode with wind turbine curtailment to reduce DC current below the DRU bypass threshold. After stable, low-power operation, the DRU is integrated. The onshore MMC then restores rated DC voltage and disconnects the transformer, allowing gradual wind turbine reconnection to complete black-start. The simulation results confirm the approach’s feasibility under conditions where all wind turbines operate in grid-following mode. Full article

Energy storage is crucial for enhancing the economic efficiency of integrated energy systems. This paper addresses the need for flexible resources due to high renewable energy integration and the complexity of managing multiple resources. We propose a decentralized collaborative multi-stage distributionally robust scheduling method for electric-thermal systems, incorporating energy storage to mitigate renewable energy fluctuations. Firstly, we model the electric-thermal system with multiple flexible resources. Uncertain parameters of renewables are estimated using conditional generative adversarial networks (CGANs), assuming empirical probability distributions. Secondly, given the distinct operators of electric and thermal systems and information barriers, we develop a data-driven distributionally robust chance-constrained optimization model (DRCCO). This model ensures decentralized collaboration without compromising information security or fairness. Then, we introduce an Alternating Direction Method of Multipliers (ADMM) algorithm with parallel regularization to decouple the model. This approach facilitates rapid solution finding with minimal information exchange. Finally, numerical examples confirm the model’s effectiveness in enhancing system flexibility and ensuring wind power consumption. Full article
