摘要：

On the premise of considering uncertainties of the parameters of different types of components in the power system, an optimal placement method for the potential parallel harmonic resonance monitoring points in the power system is proposed. Firstly, based on the harmonic resonance mode analysis (HRMA), the concept of observability of parallel harmonic resonance is introduced. Then, according to the random model of different types of component parameters, the probabilistic resonance monitoring matrix is constructed by using HRMA approach and Monte Carlo approach. Furthermore, the resonance observability index and observability-cost trade-off factor are defined and quantified, and on this basis, an optimal placement method for harmonic resonance monitoring points is proposed. This method can enable the placement scheme to achieve the coordination and optimization between the observability of harmonic resonance and the economics of investment cost under the condition that the number of required monitoring devices meets the investment cost limit. Finally, the proposed method is simulated and analyzed based on the IEEE 30-bus test system. The placement results obtained by the proposed method and traditional methods are compared to verify the rationality and superiority of the proposed method. © 2021 Automation of Electric Power Systems Press.
