On-line P-Q decoupled preventive control considering the operating cost.

Scheduling of Preventive Maintenance for Generating Unit Considering Cost

Traditional maintenance planning is based on a constant maintenance interval for equipment life. In order to consider economic aspect for time based preventive maintenance, preventive maintenance is desirable to be scheduled by RCM(ReliabilityCentered Maintenance) evaluation. So, Markov state model is utilized considering a stochastic state in RCM. In this paper, the Markov state model which ca...

Cost-Variability-Sensitive Preventive Maintenance Considering Management Risk

Traditional preventive maintenance policies, such as age replacement, periodic replacement under minimal repair, and replacement policy N, are all studied based on the expected cost criteria without considering the management risk due to the cost variability. As a result, these policies could be significantly beyond the anticipated maintenance budget allocation and lead to crisis. In order to s...

Cost of Cheap Decoupled

It is known that requiring a controlled system to be decoupled may increase costs in terms of some performance measures. However, decoupling may be desirable from an applied perspective. This paper gives an explicit quantiication of the costs of decoupling. In particular, the average quadratic tracking error is used to quantify performance. The analysis exploits the parametrisation of all decou...

Preventive Security-Constrained Optimal Power Flow Considering UPFC Control Modes

The successful application of the unified power flow controller (UPFC) provides a new control method for the secure and economic operation of power system. In order to make the full use of UPFC and improve the economic efficiency and static security of a power system, a preventive security-constrained power flow optimization method considering UPFC control modes is proposed in this paper. First...
