Special Issue Information

Dear Colleagues,

Decarbonization of power systems highly depends on variable renewable energy (VRE), such as wind, solar PV, hydropower, etc. VRE is becoming the most important power source in power systems. However, the integration of large-scale VRE into power systems has introduced many challenges for the planning and operation of power systems due to the nature of intermittency, uncertainty, and spatial heterogeneity of VRE. For example, solar power significantly reduces the load on conventional generators during the day but not during the night, resulting in the frequent start or stop of conventional generators to match unbalanced load demand. The curtailment of wind and solar power will occur when flexible sources are not enough. Increasing accommodation for renewable energy becomes a key issue. To address the issue, the energy storage system, demand response, market mechanisms, optimal dispatching strategies, and multi-energy coupling are promising technologies that can alleviate the impact of the application of VRE.

This Special Issue aims to present the latest advances related to integration and application in the use of VRE considering the planning, operation, and market aspects. It also focuses on technologies addressing the uncertainties of VRE to improve accommodation for renewable energy. Thus, scholars and researchers are kindly invited to consider submitting their original articles for consideration in this Special Issue. Topics of interest for publication include, but are not limited to, the following:

  • Renewable energy sources;
  • Smart grid;
  • Demand response;
  • Market mechanisms;
  • Environmental impact;
  • Power system dynamics and control;
  • Power system planning;
  • Hydrogen production;
  • Vehicle to grid;
  • Energy storage system.

Lithium-ion batteries (LIB) are prone to thermal runaway, which can potentially result in serious incidents. These challenges are more prominent in large-scale lithium-ion battery energy storage system (Li-BESS) infrastructures. The conventional risk assessment method has a limited perspective, resulting in inadequately comprehensive evaluation outcomes, which impedes the provision of dependable technical support for the scientific appraisal of intricate large-scale Li-BESS systems. This study presents a novel Li-BESS-oriented multi-scale risk-informed comprehensive assessment framework, realizing the seamless transmission of assessment information across various scales. The findings from a previous smaller-scale analysis serve as inputs for a larger scale. The evaluation process of this method is more scientifically rigorous and yields more comprehensive results compared to assessment technologies just relying on a single perspective. By utilizing the proposed comprehensive assessment methodology, this study utilized the emergency power supply of nuclear power plants (NPPs) as an application scenario, demonstrating the complete implementation process of the framework and conducting a comprehensive assessment of Li-BESS feasibility as an emergency power source for NPPs. Our findings propose a novel paradigm for the comprehensive assessment of Li-BESS, which is expected to serve as a scientific foundation for decision-making and technical guidance in practical applications.

With the advancement of artificial intelligence (AI) technology, the real-time measurement and control technology of power systems has also progressed. This paper proposes a correction control model for L-indexes based on voltage stability constrained optimal power flow (VSC-OPF) and a broad learning system (BLS) (BLS-VSC-OPF). This model aims to quickly assess the system’s voltage stability and accurately correct the operation mode when the voltage stability indexes are out of the security range. Firstly, the BLS is used to predict the L-index and to analyze the voltage stability of the power system. Secondly, the approximate first-order sensitivity of the L-index is calculated by the combination of the BLS and the perturbation method. This method solves the problem of the complex sensitivity derivation process in the modeling process of the VSC-OPF model. Meanwhile, when the L-index exceeds the threshold, the BLS and VSC-OPF models are combined to correct this operation mode. The feasibility of the proposed method is verified by the simulation of IEEE-30, IEEE-118, and 1047 bus systems. Finally, the BLS-VSC-OPF model is compared with the linear programming correction model based on BLS (BLS-LPC). The results show that the BLS-VSC-OPF model provides a better correction and control performance. Full article
