While traditional methods like Mixed-Integer Linear Programming (MILP) offer theoretical guarantees, they rely on approximations that can lead to suboptimal decisions and costly redispatch or penalties. Because of its inherent approximations, MILP is a low-fidelity optimization model. In this paper, we propose a multi-fidelity approach that combines MILP with a Surrogate-Based Optimization Algorithm (SBOA). MILP solutions are used as warm-starts for the SBOA, which refines the solutions using a high-fidelity simulator of PHES dynamics and redispatch costs. This allows the SBOA to handle nonlinearities and improve the initial MILP solution by exploring areas with higher expected value. Our approach is tested on a PHES unit that participates in the energy and reserve markets in Belgium. The results show that, despite the extensive efforts made in MILP modeling, decisions can still be improved through smart integration with SBOAs.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":null,"pages":null},"PeriodicalIF":8.9,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142586287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These strategies rely heavily on energy storage actuation to manage the inherent variability of RES and ensure autonomous operation. This article presents a hierarchical digital control strategy for managing distribution power systems, utilizing Battery Energy Storage Systems (BESS) to regulate voltage amplitude and enhance overall behavior for efficient energy management. At the primary control level, operating at a minute-scale actuation rate, an integral voltage regulation loop determines the BESS power injection or consumption, refined by a fuzzy conditioning of signals that accounts for the state of charge and operational modes of each device. Laplacian and random switching secondary consensus control strategies, operating at a slower rate, ensure coordinated action among individual units. The convergence of these strategies is analytically validated using Lyapunov’s theory under idealized conditions. Extensive dynamic simulations over a 24-hour period demonstrate the proposed strategy’s effectiveness in improving power quality and coordinating voltage regulation, particularly in terms of enhancing the power factor and reducing the standard deviation of voltage and power variables over time in a coordinated manner.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":null,"pages":null},"PeriodicalIF":8.9,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a Virtual Energy Storage System (VESS) model is developed to enable such industrial DRRs to participate in the DC service by coordinating with an Energy Storage System (ESS). In this VESS model, the power and energy capacity of the ESS are determined by considering its complementary characteristics with industrial DRRs, enabling the VESS to successfully provide the DC service as a whole under the proposed control strategy. Meanwhile, the operational baseline of the ESS is updated based on the “state of energy” management rules for energy-limited units as defined in the DC service.

To improve the control performance of the pumped storage governing system (PSGS), this paper introduces a hierarchical control strategy improved generalized predictive control-proportional-integral-derivative (IGPC-PID) for PSU. Firstly, we establish a precise state-space differential equation model of PSGS. Secondly, we propose a parameter approximation strategy based on the F-test, which is used to approximate the higher-order transfer function model of the PSGS. Besides, the model parameters are estimated online by the least square method (LSM) to reduce the model error. Combined with the model parameter approximation method and hierarchical control strategy proposed in this paper, numerical experiments are conducted on the simulation platform established in the study. The results indicate that the proposed model can accurately describe the hydraulic dynamic characteristics of the piping system, and the IGPC-PID can effectively inhibit the rotational speed oscillations of the PSGS under perturbation. Simulation results show that under 5 % frequency perturbation, the IGPC-PID controller can make the system reach a stable state in about 4 s with almost no overshooting. Compared with the traditional proportional-integral-derivative (PID), generalized predictive control (GPC) controller reduces about 9 s, 5 s, the overshooting amount reduces 0.0026. The stabilization time of the IGPC-PID controller is also the shortest is 3.5 s under 10 % load perturbation.

Therefore, it is essential to assess the cycle test stability of PCMs to ensure their long-term durability before integrating them into thermal systems.

The results show that NePCMs possess excellent thermal chemical stability even after 3000 thermal cycles, and latent heat (slight reduction approximately 10 %).
