🌬️ Wind Farm and Grid Frequency: Battery Droop and the Swing Equation (2D one-line view)

2D one-line diagram of a ridge wind farm feeding a small grid. Change wind, gusts, blade pitch, rotor size, demand, cable resistance, grid inertia and the battery droop gain, then watch generation, frequency, battery charge and the power-coefficient curve. Same numerical core as the 3D page, with five in-page numerical checks.
