When the share of variable renewable energy, such as wind energy, in the energy system becomes large, the integration cost increases in accordance with the depletion of flexible ramping capabilities of the system. Therefore, integration of large shares of wind power into power system operations calls for market integration as well as for additional flexibility. Among the various available options, wind power plants themselves have the technical potential of offering flexibility. Using the Danish market conditions as a case study, we model and analyze four strategies for the participation of a wind power producer in day‐ahead and real‐time electricity markets, and compare how they affect the value of wind power production. Our findings suggest that wind power plants can have a more solid business case if they are active on both day‐ahead and real‐time power markets, which increases the economic value of wind energy as well as reduces the system integration costs. We also highlight that support schemes can affect the incentives for active participation on real‐time power markets. This type of insight is valuable for wind power's potential to expand its market share while keeping a high economic value in power markets, where the political trend is towards market based deployment of renewables and focus on low system integration costs.

增加风能的价值：在多个电力市场中从被动角色到主动角色

当可变的可再生能源（例如风能）在能源系统中的份额变大时，集成成本会随着系统灵活的缓变能力的消耗而增加。因此，将大量的风力发电整合到电力系统的运行中需要市场整合以及更高的灵活性。在各种可用选项中，风力发电厂本身具有提供灵活性的技术潜力。以丹麦的市场情况为例，我们对风能生产商参与日前和实时电力市场的四种策略进行建模和分析，并比较它们如何影响风能生产的价值。我们的发现表明，如果风力发电厂在日前和实时电力市场上都活跃起来，它们的业务案例将更加坚实，这将增加风能的经济价值并降低系统集成成本。我们还强调指出，支持计划可能会影响积极参与实时电力市场的动机。这种见解对于风电在扩大其市场份额的同时保持其在电力市场中的高经济价值的潜力具有宝贵的价值。在电力市场中，政治趋势是基于市场的可再生能源部署，并着重于低系统集成成本。
