| Abstract | ||||
| The problem of control and adjustment of power system generation rampinc capability is formulated as a non-linear multi-objective constrained dispatch recognizing generation cost, transmission losses, generator operating limits, line security limits, and load uncertainly. The paper presents a novel method for economic dispatch employing Bender's Decomposition principle coupled with a successive linearization technique to provide certain generation ramping capable to follow rapidly the unexpected load changes. In such iterative scheme, the non-linear functions may be accommodated in the linear programming using updated linearization about the base case solution. The program used offers a sensitivity analysis which permits an answer to the " what if " question using about 20 % of computational time required to solve the base case. This property is attractive to power system operator. The proposed concept of power dispatch offers an efficient tool to make an economic-secure decision on whether to buy or sell regulating margin or whether to install new ramping capability. | ||||
