【摘要】：热电联产的调节能力是制约我国三北地区风电消纳的主要因素之一,储热是提高其调节能力的有效手段。该文提出一种风电场与含储热的热电联产形成共同体联合运行的调度模式,并基于该调度模式提出了考虑风电出力不确定性的联合系统优化调度模型。该模型充分利用储热带来的灵活性实现联合运行系统在上网收益和惩罚费用之间的协调,获得收益最高的风电场和热电联产联合优化运行的调度策略。仿真分析了不同运行模式下的系统运行收益,并讨论了电价因素对于运行结果的影响。该联合运行优化调度模型在我国当前电力市场改革及鼓励可再生能源调峰机组优先上网背景下,对风电场和热电厂与电网的协调运行具有重要的参考价值,能有效促进风电消纳。
[Abstract]:The regulation ability of heat and power cogeneration is one of the main factors restricting the wind power consumption in the three northern regions of China, and heat storage is an effective means to improve its regulating ability. In this paper, a joint operation model of wind farm and cogeneration with heat storage is proposed. Based on the model, an optimal scheduling model for wind power generation system is proposed, which takes into account the uncertainty of wind power output. The model makes full use of the flexibility brought by heat storage to realize the coordination between the net income and the penalty cost of the combined operation system, and obtains the optimal scheduling strategy of the wind farm with the highest profit and the cogeneration of heat and power. The operating income of the system under different operating modes is analyzed and the influence of electricity price on the operation result is discussed. This model has important reference value for the coordinated operation of wind farm, thermal power plant and power grid under the background of current electricity market reform and encouraging renewable energy peak-shaving units to get online first. It can effectively promote wind power consumption.
