This paper presents a risk evaluation based approach to the replacement strategy of aged HVDC components. It includes estimation of unavailability of individual HVDC components due to aging failures, calculation of capacity state probabilities of the HVDC system, quantified risk evaluation of the power system containing the HVDC link and benefit/cost analysis for different replacement strategies. The presented approach can be also applied to other system components. The replacement strategy for an aged submarine cable of the HVDC link in a power supply system at British Columbia Transmission Corporation has been analyzed as an example to demonstrate the actual application. The procedure of the analysis has been explained in detail in the example.

SUMMARYIn the period of transmission maintenance, the phenomenon of power interruption or even progressing to cascading failure occurs commonly just originating from one or some elements out of service. Therefore, reasonable transmission maintenance scheduling is important to ensure the safe and stable operation of power supply system. In this paper, a transmission maintenance scheduling strategy considering potential fault risk balance is proposed. Combined with the theory of value at risk and the character of potential fault, the potential fault risk index is defined to represent the possibility and risk level of the whole system power failure under the condition of the certain element failing. Meanwhile, compared with traditional transmission maintenance scheduling model, the balance index and normalized weight factor shown as the system's risk difference of each maintenance period is considered into the objective function to achieve risk sharing and real operation reliability in the whole schedule. In addition, the random potential fault simulation is applied to solve calculation problem when making the schedule. Numerical results of IEEE-118 bus system show the validity of the methodology proposed.

“…However, it did not present any mathematical method to quantify transmission system reliability. A time-shift-based Monte Carlo simulation method was described in [Li, 2004], which quantifies the impact assessment of the planned outage on whole transmission system reliability. And reference [Shahidehpour, 2000] gives very detailed mathematical formations for generation and transmission maintenance scheduling problems considering the costs as optimization objectives while satisfying various constraints including system reliability.…”
