Abstract

An algorithm for solving the power system multi-stage dynamic economic dispatch (MDED) problem in real-time is presented. The MDED problem is formulated by formally adding ramp rate constraints to the extended security constrained economic dispatch (ESCED) problem for all stages beyond the first stage. The MDED problem is then solved using the ESCED algorithm with ramp rate constraint sensitivity coefficients. A new two-component method of observing regulating margin constraints is also introduced and test results are presented comparing the one and two-stage dynamic EDC results
