Transmission Expansion Planning Method With Consideration of Demand Side Management

doi:10.11930.2015.2.128

Abstract

Abstract: With the increase of power load demand and the growing scarcity of transmission line corridor, the demand side management (DSM) has become an important way to reduce or defer the investment on power grid and power generation. In this paper, the influence of the peak load on DSM is analyzed through load duration curve and a modeling method is proposed for DSM in the procedure of transmission expansion planning(TEP). Then, a TEP mathematical formulation is built with consideration of DSM and total investment constraint. The formulation is a mixed-integer linear model which can be solved by optimization software. A case study is made to quantitively analyze the effects of DSM on the transmission planning schemes and the result has proved the effectiveness of the DSM in reducing the TEP investment.

Key words: demand side management, transmission expansion planning, investment cost, load duration curve, mixed-integer programming
