Audit and revision of the Connection Study of Wind Power Plants (99MW and 75MW) to the Transmission Network of Serbia - Power System Analysis
client: AD Elektromreza Srbije (Serbia)
type: Study
finishing date: November 2016
team: Milan Ivanovic & Milan Stojanovic – Leaders of the projects for the first and second WPP, M. Vukovic and N. Jovic - Consultants
Main objective of the analyses carried out within revision of study is to check the compliance of the wind turbines ENERCON E-115, 3MW with Serbian grid code, for the points of common coupling suggested by the Investor for these WPPs (99MW and 75MW).
In order examine compliance of the wind power plant with Serbian grid code, following activities have been performed:
- Integration of simulation model of wind power plant into regional SEE dynamic model in software PSSE and DIgSILENT and model setup for static and dynamic analyses
- Load flow analyses – network element loadings, security N-1 assessment, power losses, voltage and reactive power control
- Short circuit contribution assessment
- Transient stability – Checking the capability of wind generators to maintain stability and provide the required voltage support in cases of simulated voltage dips in the network (caused by close and remote electrical faults)
- Mid-term stability - Stability assessment after large disturbances in the power system of Serbia
- Short-term and long-term voltage stability assessment
- Small signal stability assessment
- Assessment of power quality indices in connection point – Voltage flickers (normal and switching operation), harmonic distortion
- EMT simulations - Switching transient overvoltage assessment.
