But,to our knowledge,hardly anything has been reported in
the literature on the problem of online load shedding with the
objective of minimizing system loss during generation
deficiency conditions caused by unscheduled outages in
generation and transmission system for maneuver applications
in case of emergency for distribution system.In [12] authors
applied a GA optimization method for load shedding in
distribution networks considering DG units.
This paper presents a new approach for solving the steady
state load-shedding problem in distribution network during
generation deficiency conditions with DGs.The problem is
formulated to minimize the sum of curtailed load and also
system losses.The problem is subjected to equality and
inequality constraints.The formulated optimization problem is
solved using GAs technique [1].The method is tested on a
radial distribution network with 33 load points.The effects of
GAs parameters and operators are studied.Results are
reported and discussed.
II.MATHEMATICAL MODEL OF THE PROBLEM
Load shedding problem can be formulated as an optimization
problem with the following objective function and constraints

但据我们所知,文字中对于旨在将发电不足情况下的系统损失最小化的在线甩负几乎没有任何报告,这种发电不足的状况是因预料之外的发电与输电系统断电引起的,目的是为了在配电系统遇到紧急情况时演练应用系统.
本文对于有DG时发电不足的情况下解决配电系统定态甩负问题提出了一种新的方法（或思路）.用公式表示该问题的目的是将负荷不足及协调损失的量最小化.该问题受同等和不等约束条件的制约.用公式表示最优化问题用GA技术得以解决[1].这个方法在有33个负荷点的径向配电网上进行了测试.对测试结果作了报告并进行了探讨.
II. 问题的数学模型
根据下述目标功能及约束条件,可以将甩负问题用公式表示成最优化问题：
