Abstract
Traditionally, conventional power plants have the task to support the power system, by supplying
power balancing services. These services are required by the power system operators in order to
secure a safe and reliable operation of the power system. However, as in the future the wind
power is going more and more to replace conventional power plants, the sources of conventional
reserve available to the system will be reduced and fewer conventional plants will be available
on-line to share the regulation burden. The reliable operation of highly wind power integrated
power system might then beat risk unless the wind power plants (WPPs) are able to support and
participate in power balancing services.
The objective of this PhD project is to develop and analyse control strategies which can increase
the WPPs capability to provide system services, such as active power balancing control, in a
modern power system with large scale integration wind power. This study presents the
investigation of the real-time balance control in a modern Danish power system, where WPPs
can actively contribute to active power balance control. New solutions for the automatic
generation control (AGC) dealing with the compensation of the power imbalances between
demand and generation in real time, caused by wind power forecast errors, to enhance the
security and the reliability of a power system operation with large wind power penetration with
the coordination between combined heat and power plants (CHPs) and WPPs are developed and
analysed.
The main results of this research work show that the WPPs can actively contribute to power
balance control through primary and secondary response. The integration of WPPs control into
the AGC is of high relevance, particularly in situations when wind power is contributing highly
to the total electricity production and conventional power plants are operating on the minimum
level. The grid support services from WPPs improve the active power balance control and make
power system operation more reliable.
