Optimise electrical interconnection of your power plants
Conventional power plants, wind farms and solar power plants need to be connected to the transmission and distribution of national grid systems in line with the interconnecting utility’s regulations and requirements.
Connection to the grid is critical for the delivery of reliable, high-quality electrical power, which determines the revenue, profitability and viability of power plant projects. Investors, developers and operators face challenging decisions on how and where to join the electrical connection system to the grid, as well as how to assess potential impact on the electrical transmission network. They need in-depth technical expertise to help find the optimal grid connection options to ensure a financially viable project.
Analysis of grid connection conditions
TÜV SÜD supports your power plant with network connection feasibility, design review of cable systems, optimal choice of connection circuit route, voltage level, estimation of connection costs as well as other technical challenges and solutions.
Grid connection application
We ensure that your connection application is submitted with the required technical information and coordinate the grid connection with your network operator or utility company.
Technical requirements for grid connection
Our experts identify and collate all technical requirements to obtain a clear basis for the project design and review technical aspects of the connection agreement and any power purchase agreement.
Device grid compatibility
We evaluate devices for compliance with relevant codes and requirements, and propose technical solutions if additional facilities are required.
Verification of compliance with the applicable network ratings
TÜV SÜD checks for any factors that could affect compliance, including load capacity of cables and transformers, voltage fluctuations of any kind, increase in short-circuit rating and short-circuit current, rapid voltage fluctuations causing flicker (long-term flicker), harmonics and sub-harmonics, and interference with audio frequency ripple control systems.
Analysis of load-flow, short-circuit current and selectivity
Our experts provide load-flow analysis for the design of electrical equipment, calculation of short-circuit current to verify compliance with protective measures, review/preparation of protection plans, adjustment recommendations for power plant cable systems, selectivity analysis to minimise downtime in the event of failures, calculation of the harmonic load flow, analysis of impedance-frequency response to prevent resonance, and power quality calculations.
Analysis of power loss, cable sizing and installation method, optimisation
TÜV SÜD helps you identify the energy loss for each individual network component or cable run based on load-flow analysis and calculates electrical losses within the site.
We perform economic assessment of power cable sizes and power losses during the project lifecycle.
Our specialists provide expertise on load capacity and minimum cross section, power loss minimisation/reduction, cable installation, transformer selection and improvement of cost-effectiveness.
