背景技术Background technique

近年来,随着我国用电需求的不断扩大,我国新能源发电也正在快速发展。新能源发电有多种类型,一般较为普遍的为风力发电和光伏发电,而这两种发电类型在我国应用较为广泛,为全国各省级电网提供了较多的能源。与此同时,我国新能源消纳面临着严峻的形式,2016年全年弃风电量高达49.7TWh,平均弃风率高达17%。可见,提升新能源消纳水平刻不容缓。In recent years, with the continuous expansion of my country's electricity demand, my country's new energy power generation is also developing rapidly. There are many types of new energy power generation, generally wind power generation and photovoltaic power generation are more common, and these two types of power generation are widely used in my country, providing more energy for provincial power grids across the country. At the same time, my country's new energy consumption is facing a severe situation. In 2016, the abandoned wind power was as high as 49.7TWh, and the average abandoned wind rate was as high as 17%. It can be seen that it is urgent to improve the level of new energy consumption.

根据我国风、光资源分布情况,大规模集中式开发是新能源发电的主要形式,新能源基地大多远离负荷中心,需要大规模远距离输送。由于新能源发电具有间歇性、波动性的特点,需要电网调度对其有功功率进行实时调节,以保证电力系统安全稳定运行。随着近些年新能源装机容量的快速增长,因调峰困难导致弃风、弃光的问题日益突出。可见,为了在调峰困难时充分利用电网的消纳能力,尽量减少弃风、弃光,同时避免外送断面越限,成为了当前的一个重要研究课题。According to the distribution of wind and light resources in my country, large-scale centralized development is the main form of new energy power generation. Most of the new energy bases are far away from the load center and require large-scale long-distance transmission. Due to the intermittent and fluctuating characteristics of new energy power generation, grid dispatching is required to adjust its active power in real time to ensure the safe and stable operation of the power system. With the rapid growth of new energy installed capacity in recent years, the problems of curtailment of wind and light due to difficulties in peak regulation have become increasingly prominent. It can be seen that in order to make full use of the consumption capacity of the power grid when peak regulation is difficult, minimize the curtailment of wind and light, and at the same time avoid the transgression of the outgoing section, it has become an important research topic at present.

为了使本领域的技术人员更好的了解本发明,下面列举一个更为详细的实施例,如图3所示,本发明实施例提供一种风力发电及光伏发电的有功指令协同控制方法包括:In order for those skilled in the art to better understand the present invention, a more detailed embodiment is listed below, as shown in Figure 3, the embodiment of the present invention provides a method for cooperative control of active power commands for wind power generation and photovoltaic power generation, including:

步骤301、获取各输电断面系统向总电网输电的历史数据。Step 301. Obtain historical data of power transmission from each power transmission section system to the general power grid.

此处,该历史数据包括输电断面系统中的各发电场是否属于特许权发电场,以及各输电断面系统的弃风率和弃光率。Here, the historical data includes whether each power plant in the power transmission section system belongs to a concession power plant, and the curtailment rate of wind and light in each power transmission section system.

步骤302、将包含特许权发电场的输电断面系统的优先级确定为最高优先级。Step 302. Determine the priority of the transmission section system including the concession power plant as the highest priority.

步骤303、将除所述最高优先级系统的其他输电断面系统的弃风率和弃光率按照从大到小顺序排列,并设置弃风率和弃光率较大的输电断面系统的优先级较高,确定各其他输电断面系统的优先级。Step 303. Arrange the wind curtailment rate and light curtailment rate of other transmission section systems except the highest priority system in descending order, and set the priority of the power transmission section system with higher wind curtailment rate and light curtailment rate Higher, to determine the priority of each other transmission section system.

步骤304、根据所述最高优先级和各其他输电断面系统的优先级,向所述总电网进行输电。Step 304, transmit power to the general power grid according to the highest priority and the priorities of other power transmission section systems.

一般情况下,按照优先级从高到低的顺序来向总电网进行输电。这样,若输电断面系统的弃风率和弃光率较大,则输电断面系统的优先级较高,可以优先向总电网进行输电,避免了弃风弃光现象的普遍发生。例如,图1中所示的电力系统,风力发电场A、B为特许权风电场,由断面1送出,风力发电场C、D及光伏发电场E因断面2容量有限,有长期弃风、弃光现象,风力发电场F及光伏发电场G所在断面3不受限,不存在弃风和弃光现象。则发电优先级顺序依次为:断面1对应的发电场>断面2对应的发电场>断面3对应的发电场。当调峰困难限电时,优先级较大的输电断面系统优先向总电网输电。Generally, power is transmitted to the general grid in descending order of priority. In this way, if the wind and light curtailment rates of the power transmission section system are relatively high, the priority of the power transmission section system is higher, and power can be transmitted to the general grid first, avoiding the common occurrence of wind and light curtailment. For example, in the power system shown in Figure 1, wind farms A and B are concession wind farms, which are sent from section 1, and wind farms C, D and photovoltaic farm E have long-term wind curtailment due to the limited capacity of section 2. The phenomenon of light abandonment, the section 3 where the wind farm F and the photovoltaic power plant G are located is not limited, and there is no wind and light abandonment phenomenon. Then the power generation priority order is as follows: the power field corresponding to section 1 > the power field corresponding to section 2 > the power field corresponding to section 3 . When peak regulation is difficult and power is limited, the transmission section system with higher priority will transmit power to the general power grid first.

步骤305、获取一输电断面系统内的各发电场接收到的有功指令之和。Step 305. Obtain the sum of the active power commands received by each power plant in a power transmission section system.

步骤306、判断一输电断面系统内的各发电场接收到的有功指令之和是否超出预先设置的断面安全极限阈值。Step 306 , judging whether the sum of active power commands received by each power plant in a power transmission section system exceeds a preset section safety limit threshold.

若该输电断面系统内的各发电场接收到的有功指令之和超出预先设置的断面安全极限阈值,则执行步骤307。若该输电断面系统内的各发电场接收到的有功指令之和未超出预先设置的断面安全极限阈值,则执行步骤308。If the sum of the active power commands received by each power plant in the power transmission section system exceeds the preset section safety limit threshold, step 307 is executed. If the sum of the active power commands received by each power plant in the power transmission section system does not exceed the preset section safety limit threshold, step 308 is executed.

步骤307、根据各发电场的实时出力的比例下调各发电场对应的有功指令。在步骤307之后,返回执行步骤305。Step 307: Down-regulate the active power command corresponding to each power plant according to the real-time output ratio of each power plant. After step 307, return to step 305.

例如当前需要下调10MW,而断面1对应的风力发电场A、B的实时出力分别为70MW和30MW,则比例为7:3,则风力发电场A的有功指令可下调7MW,风力发电场B的有功指令可下调3MW。For example, it is necessary to reduce 10MW at present, and the real-time outputs of wind farms A and B corresponding to section 1 are 70MW and 30MW respectively, the ratio is 7:3, then the active power command of wind farm A can be lowered by 7MW, and that of wind farm B The active command can be lowered by 3MW.

步骤308、该输电断面系统中有光伏发电场,根据该输电断面系统中的光伏发电场的装机容量及发电能力增加光伏发电场的有功指令,并控制光伏发电场向光伏发电场所处的本地进行供电,并控制光伏发电场不向所述总电网进行输电。在步骤308之后继续执行步骤309。通过控制光伏发电场向光伏发电场所处的本地进行供电,并控制光伏发电场不向所述总电网进行输电,可以避免光伏发电场的弃光率过大的现象。Step 308: There is a photovoltaic power field in the power transmission section system, and the active power command of the photovoltaic power field is increased according to the installed capacity and power generation capacity of the photovoltaic power field in the power transmission section system, and the photovoltaic power field is controlled to transmit electricity to the local photovoltaic power generation site. supply power, and control the photovoltaic power plant not to transmit power to the general power grid. Step 309 is continued after step 308 . By controlling the photovoltaic power field to supply power to the local area where the photovoltaic power generation place is located, and controlling the photovoltaic power field not to transmit power to the general power grid, it is possible to avoid the phenomenon that the photovoltaic power field's light curtailment rate is too high.

由于风力发电及光伏发电具有波动性,突然来风或来光时个别场站存在短时超有功指令发电现象,因此需要通过下面的步骤309至步骤311来进行调节,具体过程如下:Due to the volatility of wind power generation and photovoltaic power generation, when the wind or light comes suddenly, some stations have a short-term super active power generation phenomenon, so it needs to be adjusted through the following steps 309 to 311. The specific process is as follows:

步骤309、获取一预先设置的指令周期的各输电断面系统内的全部发电场的总出力。Step 309 , obtaining the total output of all power plants in each power transmission section system in a preset instruction period.

步骤310、判断所述总出力是否大于一预先设置的调峰目标值。Step 310, judging whether the total output is greater than a preset peak-shaving target value.

若所述总出力大于所述预先设置的调峰目标值,执行步骤311。若所述总出力小于等于所述预先设置的调峰目标值,执行步骤312。If the total output is greater than the preset peak shaving target value, step 311 is executed. If the total output is less than or equal to the preset peak shaving target value, step 312 is executed.

步骤311、在所述预先设置的指令周期内根据全部发电场中的每个发电场实时出力的比例下调各发电场对应的有功指令。在步骤311之后,执行步骤312。Step 311 , within the preset command cycle, adjust the corresponding active power command of each power plant according to the real-time output ratio of each power plant in all power plants. After step 311, step 312 is executed.

步骤312、确定各发电场对应的最终有功指令,并根据所述最终有功指令控制各发电场进行输电。Step 312: Determine the final active power command corresponding to each power plant, and control each power plant to transmit power according to the final active power command.
