In the face of a rapidly evolving power generation landscape, the integration of non-synchronous renewable power generation, storage, and hybrid consumers into grids is both a challenge and an opportunity. This evolution brings forth challenges such as diminished system inertial response, grid forming, frequency and voltage stability, severe faults on weak grids, black start capability, and increased voltage fluctuations. It also opens opportunities for enhancing the smart grids of the future with innovative solutions.
We navigate the process of connecting power plants to the grid. We offer an extensive range of engineering and support services, encompassing all stages from conceptual design to detailed engineering design and execution. This includes managing select or all aspects of grid connection applications, including process and documentation, acting as a liaison with Transmission Service Operators (TSOs)/ Distribution Network Operators (DNOs) to represent customer interests and reviewing connection offers to support clients in informed decision-making based on our expert judgement . Additionally, we deliver high-level OPEX/CAPEX cost estimates to identify potential risks and devise mitigation strategies.
Through our work with grid codes, regulations, and simulation software, we can conduct complex power system design and grid connection simulation studies. This ensures a thorough analysis of all factors influencing grid connection, performance, and resilience of renewable power plants. Our portfolio encompasses a diverse range of simulation studies, such as static/load flow, short-circuit, protections & selectivity, system dynamics, transient stability, small-signal stability, power quality, insulation coordination, and more. With our experience in popular and widely used tools like PSS/E, Power Factory, PSCAD, EMTP-RV, ETAP, and Matlab/Simulink, we guarantee a technically and economically optimal design, compliant with grid codes and any bilateral connection agreements.
We assist in product validation and testing, ensuring plants or equipment undergo rigorous testing before delivery to the end-user. Our partnerships with OEMs have fostered the development of various test bench setups for product or model validation. Services encompass test bench design, commissioning, collaboration with certification entities for data analysis and documentation preparation, and plant-level test plan development, followed by commissioning or post-commissioning.
Before committing to a grid connection, it’s important to have a clear understanding of the potential costs and challenges involved. We provide high-level assessments and cost estimates for grid connections, giving our clients a clear picture of the financial implications. Our assessments cover all aspects of the connection, from equipment and installation costs to ongoing maintenance and regulatory fees. We also identify potential risks and mitigating strategies, helping our clients to plan effectively and avoid unexpected costs.
Through our experience working with wind OEMs we have sharpened our understanding of the products, processes, and steps necessary for releasing new grid compliant products. We support the product development process by consolidating major global grid connection requirements, preparing design memos, identifying product evaluation gaps, enhancing processes and tools, aiding in grid model development including validation, benchmarking, and conducting certification testing analysis.
Our services include supporting controller design, integrating advanced features like Multiple dips, Frequency Control Fast Response, Low Frequency Oscillations, Grid Forming, Black Start, and pioneering control algorithms for weak grid applications. We are committed to assisting our partners in tackling the emerging challenges necessary for efficient and reliable grid operation.
Navigating the challenges of grid connection and compliance in renewable energy
Adapting to the Dynamics: The Importance of Grid Connection and Compliance
In the ever-evolving landscape of power systems, integrating new energy sources into the existing grid is similar to adjusting to complex and shifting dynamics. As renewable generation like wind and solar becomes increasingly prevalent, TSOs and DSOs are tasked with the intricate challenge of weaving these variable power sources into their systems. This effort goes beyond simple plant connection; it’s about ensuring that these new entrants can harmonize with or replace traditional power sources, all while maintaining the grid’s stability and reliability.
