Decomposition of active power supply from generators to load nodes in an electric power network

This paper presents a method for decomposing active power supply from generators in a network. A scheme that uses sub-partitioning of acyclic graph induced by optimal power flow is utilised to break a network into sub-graphs. Numerical experiment was then subsequently performed to establish the relationship between active power from generator nodes and demand profiles at load nodes. A model of IEEE 9 bus test system in PANDAPOWER 2.4.0 is used in the study. The results obtained show that, active power from generator nodes in an electric network is a linear function of load profile at load nodes.
