The invention discloses a technical economy evaluation method and device for an offshore wind power flexible direct delivery system. The method comprises the following steps: acquiring technical economy influence factors of the offshore wind power flexible direct delivery system; performing analysis based on the interpretation structure model to obtain a hierarchical structure chart; determining technical economy evaluation indexes of the offshore wind power flexible direct output system according to the hierarchical structure diagram; analyzing the evaluation indexes based on a network analytic hierarchy process to obtain a weight sequence; and performing evaluation according to weight sorting. By implementing the method, the interpretation structure model is used for analyzing the technical and economic influence factors, so that the internal correlation of the technical and economic influence factors of the flexible direct current sending-out system of the large-scale wind power plant can be eliminated to a certain extent. Meanwhile, the comprehensive benefit level of the flexible direct current sending-out system of the large-scale wind power plant is evaluated by utilizing the network hierarchical analysis model, the dependency and feedback of internal indexes of the hierarchical structure are solved, and the method is more suitable for the offshore wind power flexible direct current sending-out system with a complex network structure.
Description
technical field [0001] The invention relates to the technical field of flexible direct current transmission, in particular to a method and device for evaluating the technical and economical efficiency of an offshore wind power direct transmission system. Background technique [0002] Since the 1970s, due to the combined effects of the oil crisis and climate change, the idea of sustainable energy development has gradually become the consensus of the international community, and the development and utilization of renewable energy has increasingly received great attention from all countries in the world. Since the beginning of the 21st century, the problems of energy security and environmental protection have become increasingly prominent. All countries in the world regard the new energy industry as a key solution to energy and environmental problems, and even regard it as a new economic growth point. As a clean and renewable energy source, wind power has been valued by count...
