AbstractIt is common for power system behavior to be expressed in terms of polar voltage coordinates. When applied in optimization settings, loss formulations in polar voltage coordinates typically assume that voltage magnitudes are fixed. In reality, voltage magnitudes vary and may have an appreciable effect on losses. This paper proposes a systematic approach to incorporating the effects of voltage magnitude changes into a linear relaxation of the losses on a transmission line. This approach affords greater accuracy when describing losses around a base voltage condition as compared to previous linear and piecewise linear methods. It also better captures the true behavior of losses at conditions away from the flat voltage profile.
