Abstract:
The method for configuring the network of a factory energy management system (FEMS) includes receiving a parameter set for configuration of the network, generating a diagram based on a characteristic for the parameter of each of communication schemes available for configuration of the network, determining, based on the diagram, a communication characteristic matrix including a characteristic value representing the characteristic for the parameter of each of the communication schemes, determining a correlation matrix representing a weight for the parameter in each process to be managed by the FEMS, deriving a communication adaptability matrix by applying the weight corresponding to the parameter for each process of the correlation matrix to the characteristic value for the parameter of each of the communication schemes included in the communication characteristic matrix, and determining a communication scheme to be applied for each process from among the communication schemes using the communication adaptability matrix.
Abstract:
An apparatus and a method of correcting meter data for enhancement of electricity data management in a remote automatic measuring environment of a photovoltaic module are disclosed. According to an exemplary embodiment, a meter reads energy usage of a consumer and transmits meter data on the energy usage to an automatic meter reading (AMR) server. A meter data management system monitors an error in the transmitted meter data and a non-reading interval and re-requests collection of an error in meter data and a non-reading interval to the AMR server. When an error and a non-reading interval are found even after meter data is collected on the re-requesting, the error in the meter data and the non-reading interval are corrected using an estimated approximate value based on a history of previous meter data accumulated in a database of the AMR server.
