ECONOMIC OPERATION AND PLANNING OF MULTIAREA INTERCONNECTED POWER-SYSTEMS

OPF for both operations and planning has been exhaustively dealt with over the last few decades. In large interconnected systems, local area optimization is more solutions, while the optimization interconnected system in order to solve a local area problem is unnecessary. In this paper, an optimization tool to solve either the operations or the planning problem using partitioned optimization Is presented. Its features also automatic selection of objective for each local area and the facility to select constraints specified set. The Quadratic Interior Point extended to handle non-linear constraints is used in the optimization. It is concluded that the OFF package described in this paper handles in one environment, many issues that are not commonly dealt with in available OPF programs. Its production grade version incorporating the Bonneville Power Administration power flow (BPAPF) will he a very useful tool to the power industry.
