Ongoing Curtailment Assessment for BESS and PV
We are currently engaged in a dynamic curtailment study for Battery Energy Storage Systems (BESS). In this ongoing project, we are pioneering the development of a scripted time-series simulation tool that seamlessly integrates grid constraints with historical power flow data. Our objective is to precisely estimate the curtailment of a BESS under various operational scenarios, particularly during frequency response operation.
By leveraging cutting-edge simulation techniques, we aim to provide results that offer a more realistic and nuanced perspective compared the highly conservative estimates provided by Distribution Network Operators (DNO). This approach is designed to yield insights that could significantly impact the project feasibility, offering our clients a more accurate assessment of the potential curtailment and enabling informed decision-making in the dynamic landscape of energy storage. At Zero Grid Consulting, we are committed to pushing the boundaries of innovation to optimize the performance and viability of renewable energy projects.
Grid Code Compliance Studies
Zero Grid Consulting has successfully conducted G99 and Grid Code compliance studies for Photovoltaic (PV), wind farms, and Battery Energy Storage Systems (BESS). Our comprehensive studies include:
Voltage Fluctuation, Flicker and Unbalance (ER P28 and ER P29) where we assess the impact of renewable energy installations on voltage fluctuations, flicker and unbalance, ensuring compliance with ER P28 & P29 standards.
Harmonic Studies (G5/5) and Filter Design: Zero Grid Consulting conducts in-depth harmonic studies and designs effective filters to mitigate harmonic distortions, ensuring compliance with relevant grid code standards.
Fault Ride Through and Fast Fault Current Injection by assessing the capability of PV, wind farms, and BESS to withstand and respond to faults, meeting the stipulated fault ride-through requirements and addressing fast fault current injection considerations.
Voltage Control and Reactive Power Stability
Frequency Response (LFSM-O, LFSM-U, FSM)
Our commitment to excellence ensures that clients receive thorough and accurate assessments, guiding them towards grid code compliance and the seamless integration of renewable energy systems into the grid infrastructure.
Offshore Windfarm Reactive Power Capability Studies
In this study, we evaluated the reactive power capability of an offshore windfarm located in the North of Germany, considering diverse operational scenarios. Our assessment extended to identifying the required reactive power compensation equipment both on the offshore platform and onshore. To streamline the design, we developed a scripted tool to facilitates the optimal selection of reactive compensation and minimise the loading on the subsea cable.
BESS Voltage Step Change Modelling during Frequency Response
At Zero Grid Consulting, we bring specialized expertise in Battery Energy Storage System (BESS) Voltage Step Change Modeling during Frequency Response. Utilizing state-of-the-art DIgSILENT PowerFactory software, we conducted a comprehensive study, assessing both full active power swing and full reactive power swing scenarios.
The study focused on evaluating the size of the voltage step change and its conformity to ER P28 limits. In instances where the limits were exceeded, we calculated the maximum active power swing and reactive power available for frequency response and reactive power services.
Stability Pathfinder 2 Feasibility Study for BESS
Zero Grid Consulting proudly presents its successful project experience in delivering a Stability Pathfinder 2 Feasibility study for a Battery Energy Storage System (BESS) site connected on the transmission system in Scotland. Our team executed a thorough analysis using Electromagnetic Transient (EMT) simulations, showcasing that the BESS possesses the capability to deliver both inertia response for system frequency regulation and system strength support by injecting reactive current in response to voltage fluctuations.
The study conclusively demonstrated that the BESS site meets all the stringent Stability Pathfinder criteria.
