1.5GW PV plant: Design and Power System Studies

To examine the grid impact of a 1.5GW PV plant, we conducted a load flow analysis and a subsequent short circuit analysis to evaluate fault conditions. We then verified adherence to grid standards and identified required mitigation strategies for potential issues using dynamic modeling and RMS simulations. We specifically focused on power quality assessment, particularly on harmonic content and flickers using PSS/E and PSCAD.

NEOM Transmission System Planning

Key task for this project was optimizing the generation and storage mix for NEOM, aiming to establish a stable and reliable electricity grid. Our work involved ensuring a balanced supply-demand dynamic throughout the year, even during severe conditions such as extended sandstorms. To achieve this, we identified key tasks, employing methodologies that included load flow studies and contingency analysis. Our analysis encompassed various energy sources, including solar, battery energy storage systems (BESS), wind, and high-voltage direct current (HVDC) modeling, specifically tailored to the NEOM transmission network. This comprehensive approach enabled us to enhance the overall efficiency and resilience of the electricity system.

AMAALA Network: Power System Study

AMAALA project involved developing a detailed simulation model of the network, encompassing key substations and microgrid components, including PV, BESS, and ICE systems. Utilizing industry-standard software like PSCAD and DIgSILENT PowerFactory, we ensured compliance with the Saudi Arabia Grid Code and AMAALA Technical Requirements.We conducted a comprehensive range of studies, including load flow analysis, contingency analysis, dynamic stability assessments, and protection studies, along with specialized evaluations for PV plants and BESS. Ultimately it was decided to proceed with around 200MW of PV and 160MW of BESS. Our work also included energy system modeling and techno-economic assessments to optimize generation capacities. This extensive analysis supports the project's goal of establishing a reliable and efficient electricity grid for the AMAALA development.

Transmission studies for 765kV transformer substation

In certain parts of the world, winter season can be quite challenging due to the high reactive power in the grid, specifically in operation scenarios where system demand is at its lowest. Our task was examining and validating proposed equipment for mitigating excess reactive power issues, through set of EMT simulations. Observed phenomena include: switching studies and temporary overvoltage studies using PSCAD.

Disturbed system stability after RE integration

To ensure compliance with the National Grid Code, we rigorously analyzed the performance of a synchronous compensator using PSCAD software. Originally installed to address system inertia issues caused by the integration of large-scale renewable energy sources, the synchronous compensator helps stabilize voltage and support grid reliability. However, its use can lead to increased fault levels, which may pose challenges for grid stability, which is why it should be thoroughly analyzed.

Maximum Allowable Short-Circuit Currents in the Transmission System

Go2Power reviewed the existing technical and legal regulations defined by the national TSO, outlining the requirements for calculating short-circuit currents and options for limiting them. Our work consisted of a comprehensive analysis of the current technical requirements of the transmission system, the preparation of connection studies, and the management of the transmission network. Additionally, it addressed the national TSO's obligations to users and referent documents, which dictate maximum short-circuit currents.The study emphasized the importance of considering minimum short-circuit current requirements as well. It also incorporated the demands of ENTSO-e network codes, particularly RfG, DCC, and SOGL, which establish technical requirements related to short circuits. Furthermore, a summary list of legal, subordinate, and internal regulations from similar transmission system operators were compiled, covering both maximum and minimum short-circuit currents.

Grid Code Review and Development

Go2Power successfully developed a comprehensive Grid Code for a country in the UAE, making a crucial step towards enhancing the reliability and efficiency of their electricity system. The process involved extensive collaboration with stakeholders, including government authorities, utility providers, and industry experts, to ensure that the Grid Code aligns with international best practices while addressing local conditions. This code establishes technical standards and operational protocols for power generation, transmission, and distribution, which are vital for maintaining grid stability and facilitating renewable energy integration.Implementing the Grid Code means improved system reliability and enhanced operational efficiency. It fosters a transparent regulatory framework that encourages investment in infrastructure and innovation, ultimately benefiting consumers through increased access to sustainable energy. By laying the groundwork for a robust electrical grid, the Grid Code positions the country as a regional leader in energy management, driving economic growth and sustainability in the years to come.
