Description: 模型预测电流控制其控制思想基于以下原理：首先，功率变换器产生的开关状态个数有限，且通过建立模型可以预测每一个开关状态下被控变量的对应变化特性；其次，定义价值函数评价被控变量的预测值，为判别最优有限开关状态提供依据；最后，计算出每一种开关状态下的价值函数值，以此评价每一种开关状态下被控变量预测值的优劣，选择出最优的开关状态并应用。(The control idea of model predictive current control is based on the following principles: firstly, the number of switching states produced by power converter is limited, and the strain characteristics of controlled variables under each switching state can be predicted by establishing a model; secondly, the value function is defined to evaluate the predicted values of controlled variables, which provides a basis for judging the optimal finite switching state; lastly, the optimal finite switching state is calculated. The value function value under switching state is used to evaluate the predicted value of controlled variables under each switching state, and the optimal switching state is selected and applied.)

Description: statcom connection
Abstract In deregulated power system, congestion management
is a major problem due to operational constraints.
Flexible AC transmission systems (FACTS) devices can be
a choice to control the power flow in congested lines. This
paper explores the use of two popular FACTS devices,
TCSC and STATCOM for power flow control in electrical
network and their capability to decongest the network. It
suggests the optimal location of TCSC and STATCOM
individually to relieve congestion with minimum power
losses, voltage regulation and cost of the device. The
proposed method has been verified on IEEE-14 bus system
for its effectiveness. Simulation work is carried out in
MATLAB software.
