INTEGRATING IPPs OR DSGs INTO A UTILITY
DISTRIBUTION SYSTEM
The interconnection of IPPs (Independent Power
Producers) or DSGs (Distribution System Generation or Dispersed Storage and
Generation) to utility transmission and distribution circuits has added a new
complication to the design and operation of utility systems. Both must be
concerned that the IPP installation be designed and constructed so as to allow
safe, reliable, and economical operation.
Of special interest to the IPP owner and the
utility are the concerns that: (1) the IPP operations do not cause harm or
damage to the utility, (2) the IPP operations do not cause problems for other
customers of the utility, and (3) most importantly, that the safety of personnel
and the public is not jeopardized by the operation of the IPP.
Electric Research of State College, Pennsylvania
has the expertise and specialized test equipment to perform the following:
-
Conduct extensive model studies using both
analog and digital transient system simulators of IPP interconnections.
-
Monitor the dynamic performance of IPP
installations.
-
Predict which IPP interconnection will not
produce ferroresonance on islanding.
-
Suggest mitigation techniques for islands that
may experience ferroresonance on separation from the utility.
-
Suggest a complete interconnection protection
package which will contain overvoltage with minimal delay, undervoltage,
overfrequency, and underfrequency relays connected to operate a breaker, or
at least a contactor at the IPP if there is any possibility of overvoltage
or self-excitation occurring.
-
Provide functional tests for protective relays
using the ESEERCO test set.
Let Electric Research
assist you in the design and operation of the IPP/utility interface.
