A mathematical method of energy resources flows data validating using the state estimation theory

Abstract

The energy efficiency improvement is known to start with creating the hi-technology energy resources metering and accounting system which enables the financial mutual settlements between the parties to be improved. With data errors or data loss due to any process failures, the financial consequences may turn out to be severe. As a rule, currently existing methods for energy billing imply a posteriori detection of gross errors in the measurements, which often leads to heated arguments of the parties involved and sometimes results in litigation. The paper presents a mathematical method for monitoring the validity of metering data in the energy transportation networks. The method proposed in the paper gives an opportunity to improve the reliability of measurements of energy, to smoothen inaccurate measurements and slight inconsistencies. Also, it provides for a bad data filtering at the stage of data acquisition. Taking into account developing the production infrastructure and increasing attention being paid to energy efficiency, the methodology is very promising. © 2012, European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ).
