Analysis of the Stability and Operation Characteristics of Power Flow Operation Points for Different Power Supply Characteristic in the Distribution Systems

There are the operation modes by the access of the distributed green and clean energy of the distribution systems, which are associated with the different power supply. This paper analyzes the stability and operation characteristics of power flow method in the condition of multiple-solutions of distribution systems. Different types of power flow operation points of distribution systems have the different meanings. When the limited voltages are removed, the system will be stable in Natural operation point under the condition of minimum total energy loss according to the minimum energy theory. The research shows that when the power flow solution is stable at the natural operation point in the condition of the changed power supply characteristic, the system voltages will step up, which may affect the safe and stable operation of the system.
