Electricity theft is a major problem in developing countries and it has been very difficult for the utility companies to detect and fight against the people responsible for theft. This paper proposes an architectural design of smart meter, external control station, harmonic generator, and filter circuit, which can detect and chastise the appliances of people responsible for electricity theft. The...
Pioneering efforts in showing how electricity energy storage can be a valuable asset in a Smart Grid Distribution System have been in process for the last few years. Several demonstration projects were completed to show how substation loading could be controlled and managed to delay upgrades. The next step was to show how the load deferral benefit could be combined with distribution circuit automation...
Integration of plug in hybrid electric vehicles and electric vehicles (PHEVs and EVs) includes a wide area of topics like grid effects, different charging concepts, charger designs, harmonics from the charger etc. This short paper gives an introduction to ongoing work within this field in Sweden, and shows on research work within the topic at Chalmers University of Technology.
Asymmetric information in the electricity market creates incentive for customer aggregators (ESCOs, EMCOs, LSEs, etc.) to bid strategically as new information arrives. Such companies are pooling demand to provide enhanced services to customers. Since such demand pooling companies are not defined generically, all types of demand pooling companies will be termed demand serving company (DSC) to not confuse...
Summary form only given. The paper will discuss the details and the mission of a DOE-funded wind energy consortium for the promotion of research, education, and workforce development.
Summary form only given. Alabama Power Company has an ongoing program to improve the voltage profile of the 115 kV transmission system. This program includes the installation of a large number of distribution line capacitors. Initially, the distribution line capacitors were installed in the traditional fashion as fixed installations. However, with the wide spread deployment of Distribution Automation,...
Improvements in transmission and distribution networks can be noticed in most countries that had their system architecture changed by the deregulation process. In this new environment one of the biggest challenges is the transmission and distribution open access. In Brazil, the National Electricity Regulatory Agency has established that the monthly amount of transmission system usage contracted by...
Demand response (DR), coupled with smart-grid technologies, will be a big initiative for energy companies in the US for the next 3-5 years. This paper summarizes the key technical and IT challenges that will need to be solved to properly deploy DR at the wholesale and retail levels.
This paper will discuss the purpose and value of energy storage as a transitional technology towards SmartGrids, as well as its utilization within the future network operational arrangements. The paper will investigate assessment techniques of energy storage at a local, system and global level, with a focus on the ways that energy storage may be valued. The paper will analyse existing techniques that...
Demand Response (DR) provides mechanisms and incentives for utilities, business and residential customers to reduce energy use (and costs) during time of peak demand or when system reliability is at risk. DR is considered by CPUC, DOE and FERC as one of high-priority Smart-Grid Functionalities. FERC has developed a national action plan on demand response, recognizing that a more extensive use of demand...
The paper focuses on the importance of demand management and load control for the development of electric power system and the provision of electricity supply reliability. The potential of controllable loads in Russia is estimated including electric vehicle transport, climate systems, household, industrial and agricultural consumers. The potential and optimal volumes of perspective controllable loads...
Conventional power systems have been experiencing transition from centralized supply side management to decentralized supply&demand side management due to power system restructuring and addition of distributed generations (DGs) and Smart Grids (SGs) or Smart Distribution Systems (SDSs) with renewable power sources in the past two decades. Therefore load management under the new operating environment...
This paper outlines the reasons why COES wants to adopt the CIM standard and the road map to make its information systems compatible with CIM. COES information system is an internally developed system (SICOES), and would be the starting point to adopt CIM. It is necessary to integrate the data of the third party software used in COES for power system analysis activities to the SICOES central equipment...
After enactment of Electricity Act '2003 in India, a comprehensive change is happening in Indian electricity market, and power industries are going through a reformation process to cope with the market change. In the post Electricity Act'2003 scenario restructuring & reformation is happening very fast by unbundling the power Utility by formation different business units like GENCO (Generation...
This paper presents an overview of assessment techniques recommended by IEEE Std 519-1992 and the EuroNorm 50160-2009. It also examines reporting requirements for harmonic distortion and voltage fluctuations by the Norwegian NVE 1557 and the Colombian CREG 047 regulations. The paper also presents typical values for harmonic distortion and voltage fluctuations from the three electric utility distribution...
This paper describes some of the experiences in developing Montana Alberta Tie Line (MATL) one of the first merchant power line projects between Canada and United States. The MATL project was officially launched on February 2005 with the announcement of the first open season. It is expected to be in commercial operation by 2011. The MATL project consists of 345 km of 230kV AC transmission with power...
This informal survey classifies various transmission projects into four categories, depending on whether the project's sponsors are incumbent transmission owners or new entrants and whether the costs of the project are recovered through transmission tariffs applicable to all users or through contractual payment obligations that are voluntary assumed by willing users. The authors observe that the internal...
As an important part of Smart Grid, smart metering attracts more and more attention all over the world. It is the way for energy consumer to sense the benefit of smart grid directly. Facing the great demand of smart metering, governments and company are busy with establishing policies and standards for smart metering deployment. This paper enumerates the standards and policies set up by governments...
Summary form only given. The paper presents a new series capacitive compensation concept, which enhances power system dynamics. The idea behind the concept is a series capacitive compensation which provides balanced compensation at the power frequency while it results in phase imbalance at other frequency of oscillations. The compensation scheme is a combination of a single-phase Thyristor Controlled...
Smart Grid is a new paradigm for the complete energy ecosystem. It will drive changes that affect all aspects of power system operation - from generation to demand, and from transmission to distribution. At the philosophical level, Smart Grid manifests the continued march towards increased decentralization and empowerment, where different local entities can make “locally-Smart” decisions. Global “wellness”...
