摘要:

储热型太阳能光热发电作为一种清洁能源技术,同时具备连续平稳发电、调节功率和提供系统惯量的能力,是解决新能源发电功率波动问题的技术之一。提出了一种储热型光热发电的稳态功率近似数学模型,该模型以光照辐射度作为输入,以简化比例积分环节模拟光-热-电转换和储热过程,并考虑了输出功率控制策略。验算结果显示,该模型对实际光热电站晴天和阴天光照条件下的功率特性模拟与实测曲线吻合度较高,并可用于分析光热电站功率特性对关键参数的敏感度。

Abstract:

Concentrated solar power (CSP) with heat storage system, as a clean power, owns the capability of generating power continuously and stably, peak shaving and providing system inertia, which is one of the technologies to effectively solve the volatility of renewable energy. This paper proposed a steady state power approximate mathematical model for CSP with heat storage. This model takes the solar radiance as the input, and utilizes the simplified proportional integral to simulate the photo-thermal-electric conversion and the heat storing process, wherein the output power control strategy is considered as well. The simulation results show that the model is in good agreement with the measured curves under sunny and cloudy conditions, and can be used to analyze the sensitivity of the power characteristics of CSP power stations to key parameters.

Key words: concentrated solar power (CSP), heat storage, steady state power, approximate mathematical model, sensitivity analysis
