8人抢答器
说明： 基于AT89C51单片机设计制作一个抢答器，具体要求如下：
1、 设计一个智力竞赛抢答器，可同时共8名选手参加比赛，编号为1、2、3、4、5、6、7、8，各用一个按键。
2、 用一个按键作为主持人总开关，用来控制系统的清零和抢答的开始。
3、 抢答器开始后，数码管开始10秒倒计时，若有选手按动抢答按钮，在LED数码管上显示选手的编号，同时灯亮且伴随声音提示；倒计时完成后，选手不能在抢答；有人抢答成功后，要禁止其他选手抢答；最先抢答选手的编号一直保留到主持人将系统清零。(Based on AT89C51 single chip computer, a rush answerer is designed and manufactured. The specific requirements are as follows:
1. Designing an intelligence contest answering machine, which can be attended by 8 competitors at the same time, numbered 1, 2, 3, 4, 5, 6, 7 and 8, each with a button.
2. A key is used as the master switch of the host, which is used to clear the zero of the control system and start the rush response.
3. After the answering machine starts, the digital tube counts down 10 seconds. If a player presses the answering button and displays the player's number on the LED digital tube, the light is on and accompanied by sound prompts. After the countdown is completed, the competitor can't rush to answer. When someone rushes to answer successfully, other competitors are forbidden to rush to answer. The number of the first competitor is kept until the host clears the system.)

reactive power optimization of DG
建立了基于模型预测控制的配电网多时间尺度无功优化模型，包含日前优化调节层和实时滚动调控层。日前优化侧重于运行经济性，协调配合不同类型无功设备进行大尺度无功调节，并预留充足动态无功储备响应动态调控，降低运行风险；实时滚动调控侧重于系统运行可靠性。(A multi-time scale reactive power optimization model for distribution network based on model predictive control is established, including the optimization adjustment layer and the real-time rolling control layer. A few days ago, optimization focused on operational economy, coordinated with different types of reactive devices for large-scale reactive power regulation, and reserved sufficient dynamic reactive power reserve response dynamic control to reduce operational risks; real-time rolling control focused on system operational reliability.)
