Abstract:
1. An electricity grid infrastructure, comprising: a multi-resource offshore renewable energy platform having a plurality of renewable energy resource components configured at the platform's location, the plurality of renewable energy resource components including a plurality of wind turbines, a plurality of photovoltaic modules mounted on at least one tracker mounting system, a plurality of wave turbines, and a plurality of high-temperature solar thermal collectors mounted on at least one tracker mounting system coupled thereto, each renewable energy resource component capable of producing power from a renewable energy resource; a plurality of microgrids separately coupled to and forming an intelligent power distribution network; a distributed load management system at least configured to settle a transfer of a power requirement for a specific period of time from the multi-resource offshore renewable energy platform to be distributed to each microgrid in the plurality of microgrids so that the power requirement is satisfied from power produced from a renewable resource; and a transmission system comprising a sub-surface high voltage direct current transmission link between the multi-resource offshore renewable energy platform and the intelligent power distribution network over which the power requirement is delivered, the transmission system including a plurality of voltage source converters connecting a power output circuit of each wind turbine in the plurality of wind turbines, each photovoltaic module in the plurality of photovoltaic modules, each wave turbine in the plurality of wave turbines, and each high-temperature solar thermal collector in the plurality of high-temperature solar thermal collectors to a common direct current bus to provide the high voltage direct current transmission link with rectified alternating current power output and direct current power output regardless of whether a power output circuit produces alternating current or direct current.
