俄罗斯方块游戏的c++简单实现，参考学习很有价值(Tetris game c++ simple realization, learning valuable reference)

说明：  python基础课程；python是一种计算机编程语言。作为一种面向对象的动态类型化语言，它最初被设计用来编写自动脚本（shell）。随着版本的更新和新语言功能的增加，它越来越多地被用于独立的大型项目的开发中。(Python Basic Course; Python is a computer programming language. As an object-oriented dynamic typed language, it was originally designed to write automated scripts (shells). With the updating of versions and the addition of new language functions, it is increasingly used in the development of independent, large-scale projects.)

基于PSIM的三相光伏并网逆变器的仿真，电压空间矢量脉宽调制，双环控制(Simulation of three phase photovoltaic grid connected inverter based on PSIM)

虚拟同步机技术是将分布式电源、电动汽车、储能以及负荷变流器模拟为旋转同步机的技术，使得电力电子变流器能够像同步机一样具有大电网的同步机制，从而实现电力系统的自主运行。虚拟同步机技术为解决集中式风光消纳、大规模分布式能源、电动汽车和储能为电力系统带来的一系列挑战提供了一条崭新的思路和解决方案。(Virtual synchronous machine technology is a technology that simulates distributed power supply, electric vehicle, energy storage and load converter as rotary synchronous machine. It makes power electronic converter have synchronization mechanism of large power grid like synchronous machine, so as to realize the autonomous operation of power system. Virtual synchronous machine (VSM) technology provides a new way of thinking and solution to a series of challenges brought by centralized solar energy absorption, large-scale distributed energy, electric vehicles and energy storage for power system.)
