与系统连接的间歇性可再生电力渗透率的增加将增加对频率调节服务的要求。如果这些服务是由部分负荷运行的传统电厂满足的，这不仅会降低系统的运行效率，还会限制系统适应可再生能源发电的能力。这项工作量化了动态需求(DD)概念的价值，使家用制冷设备能够通过先进的随机控制算法对一次频率调节做出贡献。利用包括频率调节和备用服务调度在内的高效发电调度模型，确定了DD提供频率响应的好处，适用于各种未来的低碳发电系统。该分析还考虑了风力发电对系统惯性和一次频率调节的潜在影响。模拟表明，在高透风率的系统中，DD的好处显著增加，使DD成为显著提高系统效率的一个有吸引力的选择。
Increase of penetration of intermittent renewable power connected to the system will increase the requirements for frequency regulation services. If these services are met by conventional plant running part-loaded, this will not only reduce the system operational efficiency but will also limit the ability of the system to accommodate renewable generation. This work quantifies the value of Dynamic Demand (DD) concept, which enables domestic refrigeration appliances to contribute to primary frequency regulation through an advanced stochastic control algorithm. The benefits of DD providing frequency response are determined for a wide range of future low-carbon generation systems, using an efficient generation scheduling model which includes scheduling of frequency regulation and reserve services. The analysis also considers the potential impact of wind generation on system inertia and primary frequency regulation. Simulations indicate that the benefits of DD increase considerably in systems with high wind penetration, making DD an attractive option for significantly improving system efficiency.
