Optimise the Electrical Interconnection of Your Power Plants
Power grid services refer to the various functions and services provided by the electric power grid, including transmission and distribution of electricity, and balancing supply and demand.
Utility companies provide grid utility services, such as the generation, transmission, and distribution of electricity and natural gas. These services may also include metering, billing, and customer service.
In addition to providing the necessary electrical infrastructure for all kinds of power plants (conventional, wind, solar), grid utility services ensure that the power generated reaches sub-stations.
Grid services help to optimise grid connections of power plant projects, creating robust and cost-effective electrical systems. These systems are essential to successful power gathering and export to the grid system.
Power grid services are important for several reasons:
1. Reliability: They ensure that electricity is delivered to customers reliably and consistently.
2. Efficiency: They help to balance supply and demand for electricity, which helps to reduce costs and improve the overall efficiency of the power system.
3. Integration of renewable energy: They enable the integration of renewable energy sources such as solar and wind power into the grid, which helps reduce dependence on fossil fuels and greenhouse gas emissions.
4. Economic development: A reliable and efficient power grid is crucial for economic development, enabling businesses and industries to operate and grow.
5. Quality of life: Access to reliable and affordable electricity is essential for modern life, powering everything from homes and businesses to hospitals and transportation.
Power grid maintenance refers to the ongoing process of inspecting, repairing, and upgrading the infrastructure of the electric power grid. This includes maintaining and replacing power lines, transformers, and other equipment, as well as monitoring and controlling the flow of electricity to ensure that it is safe and reliable.
Power grid management involves coordinating and controlling the power grid, including generating, transmitting, and distributing electricity. This includes balancing supply and demand, monitoring and controlling the flow of electricity, and ensuring that the power grid operates within safe and reliable limits. Power grid management also includes forecasting future electricity demand and planning for new power generation capacity, transmission and distribution lines and storage systems.
TÜV SÜD provides a detailed analysis of your power grid connection situations and power systems. We add value to your project by ensuring that your systems comply with the interconnecting utility’s regulations and power grid requirements.
TÜV SÜD’s power grid analysis involves collecting data on various aspects of the power grid, such as power generation, transmission, and distribution, as well as data on weather conditions, electricity demand, and other factors. This data is then used to create computer models and simulations to analyse the power grid's performance and predict potential issues.
TÜV SÜD provides analyses of network connection feasibility, design review of cable systems, the optimal choice of connection circuit route, voltage level, estimation of connection costs, and other technical challenges and solutions through their grid services.
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.
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.
We evaluate devices for compliance with relevant codes and requirements and propose technical solutions if additional facilities are required.
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.
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.
Our experts identify the energy loss for each individual network component or cable run based on load-flow analysis and calculate electrical losses within site. We perform an 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.

The grid is made up of countless intricate interconnections, but it is primarily divided into three parts: electricity generation, transmission, and distribution.
The three main steps of the power grid structure are:
Generation: This is the power grid structure's first step, where power plants generate electricity. These plants convert fossil fuels, nuclear energy, or renewable energy sources into electricity.
Transmission: The next step is transmission, where the electricity generated is moved over long distances through high-voltage power lines to substations. This step helps to ensure that electricity is delivered to customers reliably and efficiently.
Distribution: The final step is distribution, where the electricity is delivered to customers through a network of lower-voltage power lines. This step is responsible for getting electricity to homes and businesses.
All these steps work together to ensure a reliable, safe, and efficient power grid that can supply customers with minimal interruption.
A grid system fault is an unexpected or abnormal event that occurs in the electric power grid, which can cause disruptions in the flow of electricity and impact the stability and reliability of the power system. A fault can occur for various reasons, such as equipment failure, human error, natural disasters, or other external factors.
Faults can be classified into different types, such as single-phase to-ground faults, line-to-line faults, three-phase faults, and more. They can occur anywhere in the grid, including generation, transmission, and distribution levels.
When a fault occurs, it can cause power outages, damage to equipment, and other problems. To mitigate the impact of faults, power grid operators have protection systems that detect faults and automatically isolate the affected areas to prevent the fault from spreading and causing further damage. These systems also help to restore power to affected customers quickly.
