Towards the extensive use of renewable energy resources: needs, conditions and enabling technologies
This chapter has justified the choice of the PTP standard for coordinating all of the equipment located in an installation as the most appropriate way of extending it to other installations in a wide geographical area. It is possible to reduce the amount of equipment equipped with GPS, but guaranteeing the synchronism with a quality equivalent to 1 ms. An intelligent network must evolve dynamically according to demand. In this context, it is essential to maintain a control of the stability of the network in a greater number of control points. The current technology has lowered the costs of high-performance electronic systems. As discussed in this chapter, PMUs or synchrophasors are an essential piece, and their integration into the IEC 61850 standard allows a local and centralised management system to be defined that cooperates with other systems located in the network, such as SPQAs and intelligent inverters.
