Incremental Conductance

Maximum Power Point Tracking - Classification - Incremental Conductance
... In the incremental conductance method, the controller measures incremental changes in array current and voltage to predict the effect of a voltage change ... This method utilizes the incremental conductance (dI/dV) of the photovoltaic array to compute the sign of the change in power with respect to voltage (dP/dV) ... The incremental conductance method computes the maximum power point by comparison of the incremental conductance (ΔI/ΔV) to the array conductance (I/V) ...

Maximum Power Point Tracking - Classification - Comparison of Methods
... Both perturb and observe, and incremental conductance, are examples of "hill climbing" methods that can find the local maximum of the power curve for ... The incremental conductance method has the advantage over the perturb and observe method that it can determine the maximum power point without oscillating around this value ... However, the incremental conductance method can produce oscillations and can perform erratically under rapidly changing atmospheric conditions ...
