A new distribution arrangement disposed and used in structure variable dissipated network;

In structure variable dissipated networks, distribution network planning is dealt with to this special arrangement.

For solving the question of enlarging fault-cutting region when processing the special connection using old algorithm based on the variable structure dissipated network theory, we model the switch at the joint based on the old algorithm and put forward an improved algorithm by introduci.

For the purpose of practical use a unit commitment method considering transmission losses and line overload constraint is proposed in this paper.

Thereactive load, especially the impulsive reactive load, not only increases power loss, butalso deteriorates the power quality of customers seriously, so immediate reactive powercompensation is.

Off-line simulation for Sichuan power grid under different operating conditions shows that the proposed scheme reduces power loss and is applicable for projects.
