Description

Apparatus and method for generating turbine installation scenarios for tidal power generation systems This invention relates to an apparatus and method for generating a turbine installation scenario for a tidal power generation system, which can perform a conformity assessment by virtually installing a turbine used for tidal power generation in a digital twin manner. Tidal power generation technology utilizes ocean currents to produce electricity, offering the advantage of a more stable power supply compared to offshore wind power. However, the installation of tidal power facilities entails significant technical challenges and substantial costs, making it crucial to review the optimal turbine placement based on installation locations and conditions in advance. Accordingly, there is a need for technology capable of evaluating the suitability of various turbine installation scenarios in advance by visualizing them as virtual tidal turbines and operating them through simulations, tailored to the specific characteristics of the tidal power facilities. A digital twin is a technology that creates a virtual model of a physical system or facility and simulates it to operate under the same conditions as the physical system based on real-time data. Through this, changes occurring in the actual environment can be monitored and analyzed in a virtual space, enabling performance prediction, maintenance optimization, and rapid response in the event of problems. FIG. 1 is a configuration diagram of a scenario generation device according to one embodiment. FIGS. 2 to 6 are illustrative diagrams for explaining a scenario generation and conformity evaluation method according to one embodiment. FIG. 7 is a flowchart illustrating a scenario generation method according to one embodiment. Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings. In describing the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description will be omitted. Furthermore, the terms described below are defined considering their functions in the present invention, and these may vary depending on the intentions or conventions of the user or operator. Therefore, their definitions should be based on the content throughout this specification. Hereinafter, embodiments of a scenario generation device and method will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram of a scenario generation device according to one embodiment. According to one embodiment, a scenario generation device (100) may include a communication unit (110) that communicates with an external device and an analysis unit (120) that generates one or more virtual installation scenarios for a tidal power generation system based on tidal forecast data received from an external device and calculates a suitability evaluation score for each of the one or more virtual installation scenarios. According to one example, the scenario generation device (100) can virtually install and implement a turbine used for tidal power generation in a digital twin manner, and can perform a suitability assessment including optimal turbine installation scale, turbine arrangement, power generation forecasting, and economic feasibility judgment without installing actual tidal power generation facilities. Current forecast data can be used to predict and analyze changes in currents affecting candidate areas for tidal power generation facilities. For example, an institution such as the National Oceanographic Survey provides current forecast services, and this data can be transmitted to a scenario generation device (100). Based on the collected current forecast data, the scenario generation device (100) can predict the amount of power generated at a specific point in time or period, and generate and evaluate turbine installation scenarios. In tidal power generation systems, turbines can produce electricity as blades of a specific shape, linked to a generator, rotate in accordance with the flow of the tide. There are various types depending on the installation configuration and power generation method; for example, a horizontal-axis turbine fixedly installed on the seabed can be used. Turbines can be classified into types where the direction of the blades can be changed by user command and types where it cannot. The direction-changing type can respond to changes in currents, but it has the disadvantage of high installation costs and an increased risk of failure due to its complex structure. On the other hand, the direction-changing type has a simple structure, resulting in lower installation costs and a lower risk of failure, but it has the disadvantage of not being able to respond to changes in currents. The scenario generation device (100) can implement virtual tidal power generation
