A pricing and dispatch engine for wholesale electricity market using Quadratic Programming

The purpose of this paper is to demonstrate that quadratic programming (QP) based solvers are a valid if not a better alternative to the linear programming (LP) based solvers in price based economic dispatch (PBED) engines. These engines are subject to rigorous performance and accuracy requirements when used in large size wholesale electricity markets. To date, most market clearing engine solvers are LP based. In this paper PBED is formulated as QP problem. The results of a study are shown comparing the results and performance of LP based PBED and QP based PBED on a large size test market system.
