Economic Analysis of Deep Offshore Wind Power Based on Load Similarity

Deep offshore wind power has the characteristics of high wind energy density, high power generation utilization hours, no land occupation, close to the power load center for local consumption, and a broad market prospect. However, the investment cost in the early stage is large, the subsidy intensity is gradually reduced, and it lacks the full life cycle economic analysis combined with various market policies. Therefore, this paper first proposes a systematic cost calculation method based on the comparative balance method, combined with the benefits of the wind's participation in the green electricity market and carbon trading market, considering the operating costs of thermal power, demand side response, and energy storage, a simulation model to maximize the benefit of deep offshore breeze and share the system cost of deep offshore wind power based on load similarity. Finally, through the case analysis of a 300MW wind farm, the system cost of the proposed model can be reduced by 0.41%, and electricity prices accounted for 93.4% of the total income of deep offshore wind electricity as a major supporting role. The static investment payback period of the wind farm at the current price level is about 20.1 years, which provides an important reference for the investment and construction of the profound sea breeze electric field.
