“…45 Simulation and control strategies are mainly focused on turbine mode. 46 The studies in pump mode are few and mainly focus on the safety, stability, 47 pump start and stop strategy, and cavitation characteristics of the impeller, and so forth, and rarely quantify the large amplitude regulation ability of VSPSU and the dynamic response characteristics of the system under fast speed control strategy. 48…”

Pumped storage plants (PSPs) play an important role in renewable energy consumption in power systems. Variable‐speed technology is a new and critical direction for the development of PSPs. In pump mode, variable‐speed pumped storage units (VSPSUs) have wider power regulation ranges and more flexible power responses than fixed‐speed pumped storage units (FSPSUs); however, the corresponding quantification study of VSPSUs is rare. Therefore, this study aims to quantify the static and dynamic power regulation characteristics of VSPSU in pump mode. First, the modeling of the fast speed control strategy of VSPSU in pump mode is improved. Then, the power regulation range of the VSPSU is explored. The factors (i.e., power command, governor, and converter) affecting the power response rapidity are quantified through the engineering case of a variable‐speed PSP adopting the doubly fed induction machine. Accordingly, suggestions on the settings of the parameters are provided. Quantification results show that parameter tuning based on this study effectively solves the problem of low regulation rate caused by great power fluctuations under typical power regulation cases in pump mode. This VSPSU has the fastest regulation rate of 13.75%/s when adjusting 40% power. This study could provide technical support to the practical operation of VSPSU.

Within the context of the global "dual-carbon" policy, the study explores the low-carbon energy transactions among diverse entities in the comprehensive energy market and the constraints imposed by the design of tiered carbon tax policies. This has emerged as a research hotspot in the field of low-carbon economic dispatch. The paper comprehensively examines the coupled relationship between the energy consumption and corresponding carbon emission factors among four entities: microgrid energy operators, flexible shared energy storage, electric to heat transfer operator, and community aggregator. It maps the corresponding energy prices into the interests of a non-cooperative game among entities, thereby guiding each entity to achieve a balance between carbon emissions and economic costs. The paper utilizes an enhanced genetic-particle swarm hybrid algorithm for solving and validates the effectiveness of the dispatch strategy by analyzing the marginal and cumulative effects generated by the design of tiered carbon tax policies. The findings indicate that under continuous tiered carbon tax mapping, the formulation strategy of electricity and heat prices has been further optimized, balancing the interests of the four entities, and effectively enhancing the integration of new energy while reducing the output of fossil energy units.
