WebA power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as voltages, voltage angles, real power and reactive power. It analyzes the power systems in normal steady-state operation. For a synchronous generator operating inside its D-curve, the marginal cost of providing reactive power is close to zero. However, once the generator's operating point reaches the corners of the D-curve, increasing the reactive power output will require reduction of the real (active) power.
