Inherent structural characteristic indices of power system networks

► We identified the inherent structural characteristic indices of a power system. ► We demonstrated the ease of using these indices in siting a new generator. ► A unique location for siting a new generator is identified. ► This location is indirectly connected to the weakest generator on the network. ► Have the highest potential to inject the largest active power into the network. Power equation relating an interconnected network is nonlinear and normally solved iteratively. This only gives numerical solution of a load flow without providing information on the structural relationship between buses that governs the solution that ensured. The absence of this information is an obstacle to readily solving most of power system problems. This paper seeks to overcome this limitation by proposing inherent structural indices that describe power system networks. These indices are obtained from the partitioned Y-admittance matrix based on circuit theory representation of networks. With these structural indices, an alternative method to determining the location of a new generator in a network is proposed and demonstrated.
