The HVAC system is one of the major power consuming equipment in buildings. Considering the effective setpoint temperature of each zone can increase efficiency in managing power usage in buildings, leading to the operating cost reduction. This paper presents the design of supervisory control (SC) for multi-zone HVAC systems that aims to minimize the total operating cost (TOC) and the thermal comfort cost (TCC). To minimize the TOC and TCC, both objectives are normalized and combined as a quadratic programming (QP) problem which can be efficiently solved. To achieve the design objective, two methods of SC are developed for multi-zone, namely, centralized SC and decentralized SC. We apply standard QP and sparse QP solvers using interior point method. The numerical results reveal that centralized SC performs better according to a tradeoff curve which TOC and TCC are lower. While both solvers give the same results, sparse solver can provide the solutions faster than interior point method. This paper demonstrates that centralized control is appropriate for implementation in multi-zones buildings and the sparse solver proves to be more suitable in the context of sparse QP problem.

A multi-UAV deployment method for border patrolling based on Stackelberg game

To strengthen border patrol measures, unmanned aerial vehicles(UAVs) are gradually used in many countries to detect illegal entries on borders. However, how to efficiently deploy limited UAVs to patrol on borders of large areas remains challenging. In this paper, we first model the problem of deploying UAVs for border patrol as a Stackelberg game. Two players are considered in this game: The border patrol agency is the leader,who optimizes the patrol path of UAVs to detect the illegal immigrant. The illegal immigrant is the follower, who selects a certain area of the border to pass through at a certain time after observing the leader’s strategy. Second, a compact linear programming problem is proposed to tackle the exponential growth of the number of leader’s strategies. Third, a method is proposed to reduce the size of the strategy space of the follower. Then, we provide some theoretic results to present the effect of parameters of the model on leader’s utilities. Experimental results demonstrate the positive effect of limited starting and ending areas of UAV’s patrolling conditions and multiple patrolling altitudes on the leader ’s utility, and show that the proposed solution outperforms two conventional patrol strategies and has strong robustness.

For various applications, information models described in standards are available to enable a digital data exchange. For modular process plants, where different domains are interacting in different phases of the plant lifecycle, single, existing standards are not *** this work, we analyze the most relevant standards for process engineering, namely OntoCAPE, DEXPI, and IEC 61512, in regards to their application to support the lifecycle of modular process plants, which are described in the VDI 2776 and VDI/VDE/NAMUR 2658 standards. By challenging the standards with competency questions derived from a specific use case, we discuss which information models are most suitable for all individual domains in each lifecycle phase. The result is the specification of parts of these standards which are needed to create a fully digital support for modular process plants on the example of the introduced use case.

Experimental demonstration of dynamic demand response scheduling for PEM-electrolyzers

引用

Applied Energy 2025年 393卷

作者： Keller, Roger Baader, Florian Joseph Bardow, André Müller, Martin Peters, Ralf IET-4: Electrochemical Process Engineering Jülich52425 Germany Energy & Process Systems Engineering Department of Mechanical and Process Engineering ETH Zürich Zürich Switzerland Ruhr University Bochum Chair of Process Engineering for Synthetic Fuels Bochum Germany

The use of renewable energy sources, such as wind power and photovoltaics is expected to produce fluctuating electricity prices. These fluctuations give PEM electrolyzers the opportunity to reduce costs, as they can adapt their production rates rapidly. Moreover, typically slow temperature dynamics of electrolyzers increase their flexibility for effective operational management strategies. With a defined temperature trajectory during scheduling optimization, overload operation of the electrolyzer for a given amount of time is possible. However, the temperature dynamics are typically nonlinear. In conjunction with discrete on/off decisions, temperature dynamics lead to mixed-integer nonlinear optimization problems for scheduling that are highly challenging to solve in real time. In this study, we experimentally validate the dynamic ramping scheduling optimization method that precisely linearizes nonlinear temperature dynamics using a flatness-based coordinate transformation. Utilizing the available information from the dynamic scheduling optimization a 100 kW PEM electrolyzer was operated by studying three stack temperature control methods, rejecting disturbances from load variations. Identifying a suitable control method was essential to guarantee the desired temperature tracking performance of the optimization. Our experiments show a 3.8 % cost reduction compared to the benchmark without overload operation. The designed PEM electrolyzer model also deviated only 0.6 % in costs from the experiment. Simulative scaling of PEM electrolysis to 2 MW demonstrates even higher cost reductions with the dynamic ramping method, as the larger electrolyzer has slower dynamics. © 2025 The Author(s)
