Summary form only given. The IEC 61968/70 Common Information Model (CIM) standards lay the foundation for an enterprise semantic model to achieve interoperability between the different utility domains as envisioned by the NIST Smart Grid Roadmap. Over the years the CIM has evolved as extension have been added to support new business needs and exchanges of data between these different domains. This...
Summary form only given: This paper proposes a new framework in calculating the ex post prices for the spot electricity market. The proposed method finds a set of prices that are as consistent as possible with the actual outputs of resources correctly following their dispatch instructions. Two alternative consistency metrics are proposed in the paper. One measures the difference between the actual...
Summary form only given. Demand-side management (DSM), coupled with smart-grid technologies, will be a big initiative for electric utilities and ISOs for the next 3-5 years. To meet FERC order 719, a number of ISOs are modifying their market rules to better utilize demand resources (DR). This panel session explores the key technical, economic, and IT challenges that will need to be solved to fully...
This paper discusses about CIP Version 4. Compliance with NERC Critical Infrastructure Protection (CIP) standards has become an ever increasingly complex and time consuming task for the responsibility entities subject to the requirements in the CIP standards. Existing staff workload for those tasked with monitoring, documenting and carrying out the compliance efforts have increased dramatically. Staff...
The IEC Common Information Model is maintained by a number of working groups. Working Group 16 (WG-16), Deregulated Energy Market Communications, is responsible for maintaining the packages of CIM used to support communications for market operations. This presentation summarizes the work program, including the current status and an overview of the organization and main parts of the draft models in...
Summary form only given. The NERC Critical Infrastructure Protection (CIP) standards have made a large impact on all utilities that have Critical Cyber Assets. Like many utilities, Minnkota's only Critical Asset to date has been its Energy Management System (EMS). Version 4 of the CIP standards will extend this application out to substations and power plants. Besides the large effort of bringing those...
Summary form only given. Applications of the IEC 61970 and IEC 61968 Common Information Model (CIM) have been expanding from its traditional usage in power system modeling and data exchange into the role of a standardized semantic model for the Smart Grid. The NIST Smart Grid Interoperability Road Map has identified the need for a semantically consistent framework on which to base the Smart Grid and...
The NERC Critical Infrastructure Protection (CIP) Cyber Security Standards CIP-002 - CIP-009 is a set of mandatory cyber security standards developed by the North American Electric Reliability Corporation (NERC) and approved by the Federal Energy Regulatory Commission applicable to users, owners and operators of the Bulk Power System (BPS), under Section 215 of the Federal Power Act.
The following topics are dealt with: advanced concepts for stability control; communications for the smart grid; dynamic reactive compensation; generation and transmission planning; harmonic analysis of hysteresis controllers, digital signal controllers, armature lab modeling, short circuit signatures and DC grid connections of wind machines; intelligent grid coordinating; operational methods in power...
With robust discussion at both the state and federal levels on the treatment and consideration of Demand Response, including Aggregators of Retail Choice (ARC) / Curtailment Service Providers (CSP), there are still many questions left to be answered. The debate seems to draw a definitive line in the sand and has the Independent System Operators (ISO) and Regional Transmission System Operators (RTO)...
Summary form only given. One of the key goals of the GridWise Architecture Council that is clearly identified in its interoperability framework is the ability to “bridge between communities with independently evolved understandings”. Perhaps there is no better example of the need for such a bridge than between the two most widely implemented enterprise data models in the electric utility industry,...
Has CIM crossed the chasm? While CIM is clearly well recognized in the electric utility industry, there is no easy way to measure the extent of its adoption. Gartner Inc. and EPRI teamed up to conduct an extensive global survey of CIM usage. This presentation summarizes the survey results and presents observations.
The Common Information Model (CIM) has actually been around for quite a while. To many, the CIM is simply a mechanism to exchange power flow data. However, it has become much more than that. Over the years, it has gradually evolved into a large, complex model that few completely know or understand. The purpose of the panel session is to bring out the `other' aspects of the CIM for people to see and...
Monitoring the temperature of medium and high voltage switchgear is proving to be a very important diagnostic for the protection of switchgear from catastrophic failure damage, for the prevention of expensive outages, and for the safety of switchgear technicians & maintenance personnel. In addition, monitoring the temperature of critical parts of the switchgear can increase the energy transmission...
High penetration of wind power requires reliable wind energy generation. A successful low-voltage ride-through (LVRT) scheme is a key requirement to achieve reliable and uninterrupted electrical power generation for wind turbines equipped with doubly fed induction generators (DFIGs). This paper proposes a feed-forward transient current control (FFTCC) scheme for the rotor side converter (RSC) of a...
Summary form only given. Demand Response has been a part of the ISO New England footprint since before the inception of markets in 1999. During this panel session we will identify what ISO New England issues will need to be solved to fully deploy DR at the wholesale levels. Some of the issues that will be discussed and identified are the following: What are the benefits of previously implemented DR...
Summary form only given: This paper studies real-time estimation of stability margin of a power system under disturbances by continuous measurement data. The paper presents a Ball-On-Concave-Surface (BOCS) mechanics system as a power system's adaptive equivalent representing its real-time status and the stability region about a monitored variable. The parameters of the equivalent are adaptive to the...
The Common Information Model (CIM) is a standard developed by the electric power industry that has been officially adopted by the International Electrotechnical Commission (IEC) for power transmission and distribution. The purpose is to allow application software to exchange information about the configuration and status of an electrical network. The CIM is currently maintained as a UML model. It...
Paper: Examines how storage is being used for renewable integration, where it is currently being utilized, requirements for the devices and future options.
This paper provides a summary of a presentation on “Dynamic Reactive Compensation,” for a session sponsored by the DC and FACTS Education Working Group, under the DC and FACTS Subcommittee of the T&D Committee. This paper and the presentation at the conference meant to be tutorial in nature. This paper summarizes the phases of a power systems planning study for the installation of flexible ac...
