The Kalman filter is a highly efficient recursive filter (autoregressive filter) capable of estimating the state of dynamic systems from a series of incomplete and noisy measurements. Named after its inventor Rudolf E. Kalman, this filtering method was originally designed for Gaussian-distributed systems. Later scholars developed various improvements, including the Extended Kalman Filter (EKF) which extends applicability to time-nonlinear dynamic systems through first-order Taylor series linearization.

This case study demonstrates how to use MATLAB for establishing measured natural gas operation rights in power plant portfolios, with risk assessment applications for New England power plants. The implementation involves MATLAB integration with Excel for comprehensive interface analysis. The application enables users to specify characteristics for 7 plant types, including capacity, heat rate, variable operations/maintenance costs, and minimum runtime parameters. Portfolio profitability and unit operation history can be backtested using simple dispatch strategies against historical natural gas and electricity prices. Risk metrics are computed through simulations implemented in MATLAB using gas and hybrid models, which simulate market prices for each dispatch scenario and calculate cash flows generated from plant operations based on projected electricity prices.
