  • Self-Evolutionary Optimization of Wide-Load Thermal Control Systems for Coal-Fired Power Units Driven by Digital Twins

    Hong-Wei Wang

    Under the “dual-carbon” goals, the construction of a new power system imposes requirements for deep peak regulation and flexible operation on conventional coal-fired power units. However, due to their inherent characteristics, coal-fired units face challenges such as degraded stability of thermal control systems when operating over a wide load range. Traditional control strategies struggle to adapt to complex operating conditions, necessitating a novel control paradigm. This paper proposes a digital twin–driven self-evolutionary optimization framework for wide-load thermal control systems of coal-fired power units. By deeply integrating digital twin technology, a high-fidelity virtual unit model is constructed to achieve real-time mapping and accurate prediction of the full life-cycle states of the physical entity. On this basis, a self-evolutionary mechanism is designed that integrates online identification and intelligent decision-making functions. The system can autonomously diagnose performance bottlenecks based on real-time data and historical experience, dynamically adjust control parameters, evaluate strategies through pre-simulation within the digital twin, and finally deploy optimized strategies to the physical system, forming a complete closed loop. This framework provides critical support for the efficient and stable wide-load operation of coal-fired power units and for the intelligent and green transformation of thermal power generation.

  • Ecological Flow Guarantee Mechanisms in the Modernization of Irrigation Districts

    Ting-Ting Dai

    The modernization of irrigation districts is of great significance for improving irrigation efficiency and ensuring food security, while ecological flow is a fundamental prerequisite for maintaining the stability of surrounding ecosystems and ensuring the sustainable utilization of water resources. However, in some modernization projects, excessive emphasis has been placed on irrigation while ecological considerations have been neglected, resulting in insufficient ecological flows and frequent ecological problems. This paper expounds the concepts of irrigation district modernization and ecological flow, and clarifies their interrelationship. It further analyzes the engineering, management, and climatic–environmental factors affecting ecological flows, and constructs an ecological flow guarantee mechanism by defining objectives, accounting methods, and multi- dimensional safeguard measures. The results indicate that a sound guarantee mechanism can achieve synergy between irrigation benefits and ecological benefits, providing practical reference for ecological flow protection in irrigation districts.

  • An Evaluation Model for Sponge Cities Based on the Ecosystem Services Concept

    Yi-Hui Yang

    Existing technical standards and research achievements related to sponge cities are largely concentrated on construction practices, while studies on evaluation mechanisms and systems for sponge cities remain extremely scarce. In order to construct a comprehensive evaluation system for sponge cities, this paper starts from a top-level design perspective and proposes a sponge city evaluation framework based on the ecosystem services concept. Water ecology, water environment, water resources, water security, institutional development and implementation, and visibility are adopted as first-level evaluation indicators. On this basis, feasible second-level evaluation indicators are extracted through an in-depth analysis of low-impact development (LID) stormwater systems. The analytic hierarchy process (AHP) and fuzzy comprehensive evaluation are introduced as systematic tools to establish a practical evaluation model, which is then applied to the assessment of the Yuelai Sponge City project in Chongqing.
