摘要

为构建新型电力系统，以风能和太阳能为主体的可再生能源在电网中的比例不断增加。由于可再生能源作为电源具有很强的随机性和波动性，火电机组需要频繁波动以响应系统的电力需求。为确保火电机组平稳运行，本文提出了一种考虑频谱分析的变周期日调度策略。首先，根据系统净负荷波动的特点划分不同的调度时段；其次，为使总成本最小，建立风电、太阳能、火电和储能的联合调度模型，形成变时段的日前调度计划。最后，举例说明该策略可提高火电机组的平稳运行率，并提高抽水蓄能机组的利用率。

A variable-time day-ahead scheduling strategy considering spectrum analysis

To build a new type of power system, the proportion of renewable energy sources with wind and solar energy as the main body has increased into the power grid. Due to the strong randomness and volatility of renewable energy as a power source, thermal power units need to fluctuate frequently to respond to system power requirements. To ensure the smooth operation of the thermal power units, a variable period day scheduling strategy considering spectrum analysis is proposed. Firstly, different dispatching periods are divided according to the characteristics of system net load fluctuation, secondly, to minimize the total cost, the joint dispatching model of wind power, solar energy, thermal power, and energy storage is established to form a day-ahead dispatching plan with variable time period. Finally, an example shows that this strategy can increase the smooth operation of thermal power units and improve the utilization rate of pumped storage units.

期刊介绍： Having been in continuous publication since 1977, Wind Engineering is the oldest and most authoritative English language journal devoted entirely to the technology of wind energy. Under the direction of a distinguished editor and editorial board, Wind Engineering appears bimonthly with fully refereed contributions from active figures in the field, book notices, and summaries of the more interesting papers from other sources. Papers are published in Wind Engineering on: the aerodynamics of rotors and blades; machine subsystems and components; design; test programmes; power generation and transmission; measuring and recording techniques; installations and applications; and economic, environmental and legal aspects.
