报告首先介绍了2011年西南电力库（SPP）的市场业务，包括推动电能不平衡市场的发展，引入优先使用廉价电力机制，监控每个市场参与者的电源/负荷平衡和提高系统可靠性。报告随后介绍了2014年西南电力库的集中市场情况，该集中市场将包括多天的可靠性机组启停过程、包含辅助服务在内的日内市场清算服务以及和辅助服务共同优化的实时平衡过程。随后分析了集中市场和其他市场的区别，以及集中市场的功能。(The report first describes the 2011 Southwest Power Pool (SPP) of the market business, including the promotion of energy imbalance market, the introduction of priority in the use of cheap electric power system, monitoring of each market participant the power/load balancing and improve system reliability. The report then describes the Southwest Power Pool 2014, the concentration of market conditions, the concentration of the market will include a number of days the reliability of the unit commitment process, including support services, including day services and the market clearing and support services to optimize the balance between real-time process. Subsequent analysis of the concentration difference between the market and other markets, and focus on the function of the market.)

说明：  三相光伏逆变器孤岛运行，亲测可用，毕设作业(Three phase photovoltaic inverter islanding operation, available)

分别对速度、磁场两个分量进行独立控制。通过控制转子磁链，以转子磁通定向，然后分解定子电流而获得转矩和磁场两个分量，经坐标变换，实现正交或解耦控制(The velocity and magnetic field components are controlled independently. By controlling the rotor flux, the rotor flux is oriented, and then the stator current is decomposed to obtain two components of the torque and magnetic field. Orthogonal or decoupling control is realized by coordinate transformation.)

用拟牛顿法求非线性方程组 fi( x1, x2, ?, xn ) = 0, i = 1, 2, ?, n 的一组实数解。(A quasi-Newton method is used to find a set of real solutions of the nonlinear equations.)

说明：  MATPOWER is a package of free, open-source Matlab-language M-files for solving steady-state power system simulation and optimization problems, such as: power flow (PF), continuation power flow (CPF), extensible optimal power flow (OPF), unit commitment (UC) and stochastic, secure multi-interval OPF/UC. It is intended as a simulation tool for researchers and educators that is easy to use and modify. MATPOWER is designed to give the best performance possible while keeping the code simple to understand and modify.
