Abstract

This paper develops a novel mixed-integer linear programming (MILP) model for optimal participation of battery energy storage systems (BESSs) in the Swedish frequency containment reserve (FCR) markets. The developed model aims to maximize the battery owner's potential profit by considering battery degradation and participation in multiple FCR markets, i.e., FCR in normal operation (FCR-N), and FCR in disturbances (FCR-D) for up- and down-regulations. Accordingly, a precise formulation of a detailed battery degradation model and adherence to the technical requirements of the Swedish FCR markets are incorporated into the developed model. To achieve more practical results, simulations are conducted based on one minute time step realistic data for the whole year 2022. The results show a potential profit of 708 thousand Euros for a 1MW/1MWh BESS by participating in multi-FCR market. Analyzing the impact of considering degradation in the optimization problem has shown that the annual battery aging cost could decrease by 5%-29% without a significant effect on profit. The proposed model can be practically used by flexibility asset owners to achieve profitable and sustainable operation strategies that reduce battery degradation., Comment: Submitted to IEEE Transactions on Power Systems

16. An IGDT-Based Energy Management System for Local Energy Communities Considering Phase-Change Thermal Energy Storage

Author

Mohiti, Maryam, Mazidi, Mohammadreza, Oggioni, Niccolo, Steen, David, and Tuan, Le Anh

Abstract

Local energy communities (LECs) facilitate energy distribution, supply, consumption, storage, and trading for the communities and their members. This article proposes an energy management system (EMS) for optimal heat and power scheduling in LECs. A novel model for the phase-change thermal energy storage (TES) which is applicable in mixed integer linear problems (MILP), is introduced. Furthermore, a risk-averse and risk-seeker EMS is developed that incorporates the integration of TES to optimize electricity and heat scheduling in LECs. The developed EMS doesn't require probability distribution functions of predicted data which makes it valuable in cases with high levels of uncertainties or lack of sufficient historical data. To validate the performance of the proposed TES model, real time studies are conducted on an industrial TES provided by Azelio company. Likewise, the effectiveness and efficiency of the proposed EMS are evaluated on a real LEC at Chalmers University of Technology campus, Gothenburg, Sweden.

18. A Pure Data-Driven Method for Online Inertia Estimation in Power Systems Using Local Rational Model Approach

Author

Mazidi, Mohammadreza, McKelvey, Tomas, and Chen, Peiyuan

Abstract

This article presents an online data-driven method to estimate the inertia constant of synchronous generators (SGs) and the virtual inertia of converter-based resources (CBRs), which enables time-dependent inertia tracking in the normal operation of a power system. The proposed method is based on continuous monitoring of frequency response functions (FRFs) of SGs and CBRs, which are identified by ambient wide-area measurements of phasor measurement units (PMUs). To identify FRFs, a novel non-parametric approach, namely the local rational model (LRM), is used which does not require correct model order selection. LRM approach has a low computational burden and requires a short window of data, both of which are essential for estimating time-dependent inertia using ambient data. The applicability of the proposed method is evaluated in the IEEE 39-bus system and an actual system. The results demonstrate the accuracy, robustness to noise, and effectiveness of the proposed method in estimating the time-dependent inertia of power systems.

Abstract

This paper proposes a novel energy and reserve scheduling model for power systems with high penetration of wind turbines (WTs). The objective of the proposed model is to minimize the total operation cost of the system while static and dynamic security is guaranteed by preserving the frequency nadir, RoCoF, and quasi‐steady‐state frequency in the predefined range. Likewise, a supervisory, control, and data acquisition (SCADA) system is developed which allows Vanadium Redox Flow Batteries (VRFBs) to continuously communicate and participate in the primary frequency response. To cope with the uncertainties, adaptive information gap decision theory is used that ensures a target operating cost for the risk‐averse operator of the power system. The proposed scheduling model is applied on a modified IEEE 39 bus test system to verify the impacts of the fast reserve provided by the VRFBs in the dynamic frequency security enhancement of the power system with high penetration of WTs.
