Abstract
A new method and apparatus for recursive parameter estimation which closely approximates actual values is taught. Briefly stated, the within invention estimates impedance parameters of network branches in both on-line and off-line modes, providing accurate estimation of branch parameters in the presence of noise in measurements and rejecting gross measurement errors, by use of a Kalman type Markov filter scheme using maximum likelihood estimation.
Claims5
An energy management system for recursive parameter energy management control, comprising:
- control means for changing the settings of a power grid or subsystem (grid);
- measurement means for measuring the status and settings of said (grid) and producing representative grid data thereof;
- a computer having memory means for storing said grid data and further having a program means for analyzing said grid data and producing values representative of the impedance parameters of said grid, said program means including means for separating said grid data into a plurality of sub-grid data sets, each of said sub-grid data sets containing a predetermined number of unknown grid impedance parameters and means for recursively modeling each of said sub-grid data sets into Markov processes;
- and
- comparing the impedance parameters of said grid which were derived from Markov processes recursively modeling said sub-grid data sets a predetermined grid impedance parameters.
