Data interaction model for power transaction based on CIM

With the increase of power transaction business, traditional power transaction data interaction models cannot fully meet the needs of data interaction. The data model conforming to the power transaction data architecture plays an important role. Data interaction requirements of Chinese electricity market transaction business are analyzed, and the specific method of power transaction data description is given in the IEC-61970 protocol standard. Also a common information model (CIM) for electricity trans-action data interaction is built that conforms to the data interaction architecture. Finally the functional description of the model is built adopting the unified modeling language (UML). Compared with the existing electricity transaction data interaction model, the method is beneficial to reduce the degree of data redundancy, increase the speed of data interaction, and thus improve the transaction efficiency of the electricity market.

Extension of Common Information Model of Load Storage in Regional Energy System Based on IEC61970

The need to reform the energy system is urgent. Choose new energy to supplement traditional energy according to local conditions, to build a comprehensive energy system will become more and more emerging development areas of the rigid demand. However, in the practical application of RIES, due to its high complexity and wide range of involvement, there are information islands between various equipment and systems, which cannot support its high efficiency and timeliness. Therefore, The common information model (CIM) modeling method can break the information interaction barriers between RIES.Taking a new area as an example, the CIM model expansion of photovoltaic generating electricity system, wind power system, EV charging equipment, substation class, thermoelectric conversion equipment and user load is established. The classes and class attributes required for the information interaction of RIES control center in the new area were designed, which laid the foundation for the interaction between different energy systems and the load and storage of the source network.

Scalable Storage Management Architecture for Common Information Model/Web-Based Enterprise Management Environments

Web-Based Enterprise Management (WBEM) is independent of platforms and managed resources so that it can used to unify storage management. WBEM consists of three components. Common Information Model (CIM) is the main component which utilizes a common data format, language and methodology for collecting and describing storage resources. xml CIM encoding defines the way that represents the CIM classes and instances by XML elements. CIM Operations over HTTP makes CIM operations in an open and standardized environment based on HTTP. In this paper, we propose a novel storage architecture that enhances efficiency of storage management under CIM/WBEM environments namely Scalable Storage Management Architecture (SSMA). SSMA is developed based on OpenPegasus. In addition, SSMA has better delay performance than traditional proxy CIMOM.
