A Novel Direct Method for Generator Sharing Calculation in EMS of Scada Using the Power Division Theorem for Minimum-Loss Real Time Operation

This paper presents a novel method for directly computing the sharing of each generator in a power system using the Power Division Theorem (PDT) within the Energy Management System (EMS) of Supervisory Control and Data Acquisition SCADA. Real time operational data acquired in actual values are converted into per unit values for load flow and state estimation analysis. Using these normalized quantities, the proposed approach enables immediate estimation of generator contributions to loads and losses at different system levels. The method introduces the concept of Common Source Node Voltage (CSNV) to achieve minimum-loss operation. An illustrative example demonstrates reduced system losses under the proposed constraint. The approach provides a simple and computationally efficient enhancement for real time monitoring and control in modern power systems.
