Heat capacity in single-family houses with electrical heating using heat pumps represents a storage which can be used to balance the electricity supply. It is assumed that electricity prices will reflect surplus or deficiency in production. A performance function describing cost of electricity combined hour by hour with user comfort is formulated. Minimization of this performance will balance the grid by pushing consumption towards hour with surplus production capacity. The minimization results in a power consumption schedule and a temperature schedule for each house. A number of control structures are described aiming to obtain this optimum by communicating references to either house temperature or heat pump power or by offering the consumer an hour by hour price. By simulation the schemes are compared by there ability to time shift consumption and to avoid consumer discomfort. Additionally the necessary information exchange for the schemes is discussed. Comparisons indicate that it is possible to use heat pump heated private houses to move power consumption within a time interval without loss of consumer comfort. However the full potential of the storage capacity can only be achieved in the schemes which combine feedback with an optimizing solution.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"62 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83975079","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 rated current and voltage of the HVDC are ±1200 A and ±250 kV, respectively. The diameter of the sensing head of the OCT is about 2 m and it is applicable not only to newly constructed cable heads but also to existing cable heads without disassembling a cable head bushing. The field test of the OCT was conducted at Furukawa Cable Head Station for more than one year and we confirmed long-term stability. In the field test, ambient temperature changed in the range from -15degC to 27degC. Primary current measured by the OCT was compared to that measured by a Kraemer-type DCCT, and the data were consistent. Reflecting the field test results, we manufactured the OCT for commercial installation. Factory tests of the OCT for commercial installation were conducted. Ratio error, frequency response, and the results of other tests satisfied their criteria. In particular, we measured temperature characteristics precisely and confirmed that the ratio error of the total system at any ambient temperature, including dispersion, satisfied the required specification, which is equivalent to IEC 60044-8 class 1.0.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"9 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89380909","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}

With the use of SF6, the world's first high voltage gas insulated switchgear was introduced into the market in 1968. Whilst many may consider this technology as mature, there have been continuous development-driven changes in GIS design, manufacture, test and operation. Consistent research and innovative development led to the nowadays compact and overall optimized switchgear. Today, GIS technology consists typically of a modular design and is filled with a minimum of SF6. The standardized structure is made to match various customers' specifications and allows realizing almost all substation configurations accordingly. Furthermore, it offers low life cycle costs and can be used for indoor and outdoor applications. What trends have shaped the GIS of today, and which will determine how GIS will further evolve into the future in terms of design, manufacture, test, and operation throughout its life cycle? What are the customers' visions and what are the manufacturers' answers?","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"58 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89759960","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}
