This paper presents a special case of integration of the preventive maintenance into the repair/replacement policy of a failure-prone system. The machine of the considered system exhibits increasing failure intensity and increasing repair times. To reduce the failure rate and subsequent repair times following a failure, there is an incentive to perform preventive maintenance on the machine befo...

This paper provides a description of the development of software tools able to deal with system fast dynamic monitoring and determination of preventive control procedures, for a given set of disturbances, in networks with large integration of wind power production. Preventive control is performed through power redispatches, involving also the on/off control of the wind generators. The quality o...
