Static Loads
A static load model expresses the characteristic of the load at any instant of time as algebraic functions of the bus voltage magnitude and trequency at instant.
Traditionally ,the voltage dependency of load characteristics has been represented by the exponential model;
Where P and Q are active and reactive part of the load when the bus voltage magnitudc is V .The subscript 0 identifies the values of the respective variables at the initial operating condition.With the exponents a and b equal to 0,1,or 2,the model represents constant power ,constant current,or constant impedance characteristics,respectively .For composite loads,their values depend on the aggregate characteristics of load componenents.
An alternative model which has been widely used to represent the voltage dependency of loads is the polynomial model:This model is commonly referred to as the ZIP model,as it is composed of constant impedance(Z),constant current(I),and constant power(p) components.

静态负荷
静态负荷模型用瞬时母线电压的大小和频率的代数函数来描述任意时刻的负荷特征.
传统上来讲,负荷对电压的依赖特性是用指数模型表示的：
其中P和Q是当母线电压大小是V时负荷的有功和无功部分.下角标0表示变量在初始运行状态的值.当指数a和b分别为0、1、2时,模型分别代表恒定功率、恒定电流和恒定阻抗的特征.对于复合载荷,其值取决于负荷成员的聚合特征.
另一个反映负荷的电压依赖性并应用广泛的模型是多项式模型.此模型通常被称为ZIP模型,因为它由恒定阻抗（Z）,恒定电流（I）和恒定功率（P）组成.
