Mixed‐integer linear model for transmission expansion planning with line losses and energy storage systems
In this study, a deterministic single-stage transmission expansion planning model considering line losses and deployment of energy storage systems (ESSs) is proposed. A piecewise linearisation approach using secant segments is adopted to estimate non-linear line losses, and the optimal partitioning method is studied.
