In this video, we will discuss about Sensitivities / Distribution Factors in powerfactory. dP/dP sensitivity analysis (often written as ∂P/∂P or similar partial derivatives) in power systems refers to a type of sensitivity analysis that examines how changes in active power injections (or withdrawals) at specific buses affect other quantities in the system, such as line power flows, voltages, losses, or loading margins. It is a core tool in power system operation, planning, and security analysis, derived from linearized models around an operating point (typically from the power flow Jacobian or related matrices). What "dP/dP" Specifically Means P usually denotes active power (real power, in MW). dP/dP (or ∂P_line / ∂P_injection) is the partial derivative of one power-related quantity with respect to another. Common examples: ∂P_{k-l} / ∂P_i: How much the active power flow on line (k-l) changes when active power injection at bus i changes by 1 MW (while balancing elsewhere, often at a slack or reference bus). Similar forms appear in ∂P_L / ∂P (sensitivity of total system losses to injection changes) or sensitivities in voltage stability (e.g., related to loading parameter λ in continuation power flow).
