DERs have significant potential to provide grid services, in addition to power, to improve the economics and security of grid operation. However, valuation and pricing mechanisms are needed to incentivize DERs to provide grid services. This paper proposes anew optimization model for pricing ancillary services and reactive power in distribution-level electricity markets based on the concept of distributional locational marginal prices (DLMPs). First, this paper presents a distribution market-clearing model that co-optimizes the dispatch of active power and reactive power from DERs. Next, a pricing model for joint power and ancillary services, in the form of regulation up andregulation down, is developed. Simulations and sensitivity analysis are conducted on a modified IEEE 33-node distribution network. The impacts of DER capacity, DER bidding price, and regulation reserve requirement on nodal active and reactive power and ancillary service pricing are analyzed.","PeriodicalId":360154,"journal":{"name":"2021 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124398767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The progressive, and rapid in some Countries, introduction of massive renewable resources, DC and hybrid DC/AC transmission, power-electronic controlled loads, and the increase of voltage rating of power electronic devices is going to break the axiom that power supply in electrical assets is sinusoidal AC. Emphasis is, therefore, in understanding the major problems caused by the massive introduction of new conversion technologies on grid component reliability, then to adequate the design of electrial apparatus to the quality and type of power supply. This paper focuses on life and reliability of electrical insulation, being insulation, in general, the weakest part of an electrical apparatus or device. Models to account for electrical and thermal overstresses caused by deviation from AC siuusoidal waveforms are presented in the paper, accounting for repetitive or random voltage transients, DC voltage plus ripple, harmonic voltages and currents. Application examples are discussed, to leverage the potentially dramatic effect on insulation reliability of a new, non AC-sinusoidal, paradigm of electrical grid and asset.","PeriodicalId":360154,"journal":{"name":"2021 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125060463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, even though there is a vast amount of literature which examines future evolution scenarios, scenarios which could be used for various studies across different regions are still lacking. This paper establishes systematic scenarios for how AC grids will evolve with 10 to 20 year perspective, which can be used both as a basis for long-term technology assessment as well as a guidance for transition roadmaps. In its essence, the macro trends behind the energy transition have been outlined first, and power system challenges due to the energy transition have been identified. As a next step, locations-independent scenarios are established using the cross-impact balance method, and are further mapped to the identified power system challenges. Finally, the scenarios are mapped against different regions of the world to obtain the most plausible scenario with respect to local trends.","PeriodicalId":360154,"journal":{"name":"2021 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127005076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a complex process to restore the system after a cyberattack since both cyber and physical systems need to be restored. Traditionally power system restoration is focused on recovery of the physical power system. To extend the restoration methodology to a power grid as a cyber-physical system, this paper is concerned with the restoration of the cyber system based on detection and isolation of the attacked device and recovery of the functions through collaboration among multiple devices. To this end, at the first stage, the substation automation system (SAS) recovers independently of any untrusted remote control. This paper proposes a new strategy for cyber recovery at an IEC 61850 based SAS following a cyberattack. The compromised components are isolated at the substation Local Area Network (LAN) by dynamic network reconfiguration, which is implemented with the centralized controller of Software Defined Network (SDN). Furthermore, the proposed collaborative Intelligent Electronic Devices (IEDs) are deployed to recover the main functions of the compromised device. A cyber-power system testbed with the SDN controller and commercial grade IEC 61850 code has been developed for implementation and validation of the proposed strategy.","PeriodicalId":360154,"journal":{"name":"2021 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121178539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cyber threats in electric grids have increased significantly because of the increased interconnectivity of supervisory control and data acquisition systems and public network infrastructure. As the penetration level of distributed energy resources increases, it is imperative to employ system-monitoring techniques such as state estimation for the reliable operation of distribution systems. Recently, multiple methods have been developed that exploit the low rank property of distribution system state matrix and are robust to bad data, such as matrix completion. This paper analyzes the impact of various realistic cyberattack scenarios on matrix completion. Realistic cyberattack scenarios are converted into data corruption models that are used in an extensive simulation of a custom IEEE 123-bus system.","PeriodicalId":360154,"journal":{"name":"2021 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121714105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present the networked microgrids with dynamic boundaries, technology aggregation, and resiliency service offering through a layered architecture of the EaaS delivery model.

During this mode, grid-forming units are responsible for controlling the frequency and voltage of the microgid. Hierarchical control structure based on droop control is utilized to provide these functionalities. In primary control level, the system stability is maintained through supplying required active and reactive power leaving a deviation in the frequency and voltage magnitudes. The secondary control level is introduced to restore the frequency and voltage to their nominal values. However, droop-based hierarchal control suffers from poor reactive power sharing due to voltage drop in the lines. The proposed controller aims to restore the frequency to its nominal value and voltage within a predefined limit while keeping the active and reactive power sharing difference between units to the minimum. The proposed controller employs consensus-based distributed communication where each unit only communicates with its neighbor. This paper provides optimality and consensus analysis of time-varying optimization-based consensus control as well as a design procedure of the controller. The proposed controller is validated through SIMULINK/ MATLAB simulation.

Combined heat and power (CHP) plants are $a$ promising high-efficiency distributed energy resource (DER) that can be used to improve renewable integration while simultaneously providing a host of benefits to the grid. Owing to their geographic distribution and long hours of operation, these units provide an improvement in grid resiliency during emergencies, deferred transmission system upgrades and reduced emissions. This work explores some barriers that impede grid participation of CHPs and proposes a multi-objective optimization approach for better involvement of distributed industrial CHP units at the wholesale energy market level. The CHPs considered are not third party generating units that produce power to meet their own requirements.
