While modern cryptography provides tools for addressing this challenge, it may not be enough. We propose here a method for securely updating the software controlling devices connected to an Alternating Current network that offers an added, stronger layer of protection against malicious code updates. This is achieved by allowing only the power generating authority to open a special “window” within which the devices accept such updates.","PeriodicalId":419250,"journal":{"name":"2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132790628","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 the first part of the paper outline of the FM method is given. According to the FM method a power system is represented by hierarchical model, consisting of systems of equations of subsystems (lower level) and system of equations of higher level, in which only boundary variables of subsystems are present. Next part of the paper is devoted to description of hierarchical algorithms for solution of power flow, optimization and stability analysis problems of power systems, based on the FM method. It is shown in the last part of the paper how general structure of the FM algorithms and principles of the FM method are used to form the basis, on which construction and functioning of distributed control system assuring optimal operation control in large integrated electrical power systems is founded.","PeriodicalId":419250,"journal":{"name":"2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114115379","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}

Thermal dissipation and parasitic inductance are identified as two major issues causing energy loss during transmission. Literature and industrial approaches to mitigate these issues are reviewed, which features a DC-DC inverter in hybrid electric vehicle (HEV) or plug-in hybrid electric vehicle (PHEV) as an example. A 3D package technology is therefore developed and CAD simulation tool is then employed to investigated and evaluated its effectiveness in electricity conversion. The result shows the package halves inductive parasitic with significant improvement on thermal efficiency. The implementation of this technology in automotive power converter is expected to achieve high efficient and reliable power conversion.","PeriodicalId":419250,"journal":{"name":"2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies","volume":"508 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116330839","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}

As controllable loads, they form an attractive target for active demand response, by modulating, delaying or accelerating the charging of the vehicles. As such, this can be used to balance power from renewables, to shave peaks or to spread consumption more evenly, or to minimise energy costs. Such control actions need to take dynamically varying constraints into account, concerning arrivals and departure times, grid capacity, power consumption, green electricity generation, etc. Hence a multi-objective optimisation problem needs to be solved, in order to optimise for the different criteria. By incorporating predicted trends for loads, better results can be obtained than when only considering the current situation. Agent-based decentralised and hierarchic coordination mechanisms provide such functionality in a scalable yet robust way. Modular implementation allows flexibility.","PeriodicalId":419250,"journal":{"name":"2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134081430","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}

New cyber security challenges emerge, especially related to privacy, connectivity and security management, and these need to be properly addressed. Existing cyber security technology and good practice mainly come from the traditional telecommunication environment where the requirements on safety and availability are less strict. For Smart Grids, lessons can be learned from the oil and gas industry on how they have dealt with security challenges in their implementation of integrated operations. Still, Smart Grids face a slightly different reality, due to their extensive geographical distribution and the enormous number of end-users. The contribution of this paper is a survey of cyber security challenges for Smart Grids, together with a roadmap of how these challenges must be addressed in the near future.","PeriodicalId":419250,"journal":{"name":"2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134101077","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}

Some of the parameters that cause load-induced voltage drops and the resultant ramifications to the usability of the electric network are discussed. The system needs a dynamic mechanism to control the voltage at any node each and every time a new load is connected or a load is removed from the system. This paper seeks to use smart house technology in the form of a smart grid, intelligent appliances and interactive power nodes to circumvent and mitigate these problems. The requirements and possible components that the smart grid will need to provide, are set forth. The use of power line communications over the DC electricity mains using CAN-bus or LIN-bus protocols is discussed.","PeriodicalId":419250,"journal":{"name":"2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133553226","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 untapped powerful information within the protection, control, and monitoring intelligent electronic devices (IEDs) can be leveraged. Dramatic distribution automation improvements are available by simply enabling and coordinating the unused automation capabilities of the numerous isolated IEDs already in service throughout the power system via distributed communications. These improvements automatically and rapidly isolate faults, restore power, monitor demand, and maintain and restore stability for more reliable generation, transmission, and delivery of electric power. By communicating with one another to accomplish tasks formerly done by humans or left undone, these IEDs observe the state of the power system, make educated decisions, and then take action to preserve the stability and performance of the grid. The smart grid is a collection of information sources and the automatic control systems that manage the delivery of power, understand the changes in demand, and react to it by managing demand response. This paper focuses on distribution-level protection and automation techniques illustrated with real-world case study examples.","PeriodicalId":419250,"journal":{"name":"2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129496337","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}
