PO068: Technical comparison between HVAC and HVDC solutions for power from shore and offshore wind generation applications
Eduardo Diaz, Technical Consultant, Hitachi Energy
Abstract
This study focuses on evaluating the economic feasibility of floating substation solutions for two key applications: Floating Power From Shore (FPFS) and Floating Offshore Wind Generation (FOWG). These applications are critical for reducing the environmental impact and operational costs associated with traditional offshore energy infrastructure. The report investigates multiple business case scenarios, each with distinct configurations and technological approaches. The primary objective is to compare the economic viability of High Voltage Alternating Current (HVAC) and High Voltage Direct Current (HVDC) systems in various operational contexts. The study encompasses five main cases: 1. Case 1: A single floater HVAC system transmitting 300 MW over a 100 km distance from shore. 2. Case 2: A single floater HVDC system transmitting 300 MW over a 100 km distance from shore. 3. Case 4: A multi-hub system combining HVDC and HVAC technologies, with a 200 km distance from shore to the first hub and 20 km between hubs, transmitting 200 MW from shore to the first hub via an HVDC link and 100 MW between hubs with a submarine HVAC cable. 4. Case 5: An offshore generation HVAC system transmitting 1 GW over a 50 km distance from shore. 5. Case 6: An offshore generation HVDC system transmitting 1 GW over a 200 km distance from shore. Each case is analysed in terms of Capital Expenditures (CAPEX) and Operational Expenditures (OPEX), providing a comprehensive budgetary cost indication. The analysis includes the costs associated with onshore and offshore substations, export cables, and other main equipment. Additionally, the study assesses the overall operational expenditure during the asset’s lifetime, considering maintenance activities and equipment losses. This analysis aims to identify the most cost-effective and efficient solutions for FPFS and FOWG applications and contributing to the advancement of sustainable energy infrastructure.
