Connection studies for Wind Power Plant
Short description:
Since 2006 ISPE performed the largest number of connection studies for WPP (Wind Power Plant) in Romania.
According to Romanian laws, these studies are performed in order to obtain the Connection Technical Permits and, at the end, Connection Contracts and Establishment Authorisation for the WPP.
ISPE performed connection studies for WPP with nominal power between 0.6MW and 1242MW, connected from 20kV up to 400kV grids.
Based on the experience gained, ISPE proposed grid reinforcement solutions for distribution and transmission network and, in accordance with international regulations, a set of rules for the connection of wind generators and WPP to the power system.
Based on the analysis made by our specialists, more than 99% of our connection studies have been approved by the grid operators without further comments.
Services offered:
The connection study for WPP larger than 10MW is performed in two stages:
- Stage 1 – establish several alternatives to connect the wind mill to the grid and perform preliminary analysis on these alternatives; the analysis is based on power flow and short-circuit stress calculations; the goal of this stage is to propose an optimum connection alternative to be preliminary approved by grid operators.
- Stage 2 – complete analysis according to Transmission and Distribution Technical Codes that includes: update of power flow calculations for the connection alternative preliminary approved by the grid operators, maximum and minimum short-circuit stresses calculation, static and transient stability, power quality, reliability indicators, integration in the dispatch control, contribution to voltage regulation, least-cost analysis.
Estimated economic efficiency:
Technical and economical analysis is used to compare the connection solutions and to choose the alternative with minimum grid connecting costs among those without negative impact on the power system.
Country and location:
ISPE performed connection studies in the following areas of Romania: Dobrogea (132 locations), Moldova (30 locations), Muntenia (24 locations), Banat (7 locations) and other areas.
Client:
Since 2006 ISPE performed WPP connection studies for more than 110 clients.
Start / Completion date (commissioning):
The promptitude and competence of our specialists to perform the connection studies, in order to be approved by the authorities allows our clients to complete the WPP in maximum 3 years. This period depends equally on the client to obtain the other permits (construction, environment etc.).
