Active power distribution network control strategy and method

The invention discloses an active power distribution network control strategy and method. The method includes the following steps that firstly, all circuits and distributed power source information are initialized; secondly, t is equal to zero, and initial load flow calculation preparation is conducted; thirdly, the changes of P and Q are compared, whether load changes exist or not is judged; fourthly, normal operation is conducted, and adjustment is not made; fifthly, primary adjustment of a system is conducted; sixthly, secondary adjustment of the system is conducted; seventhly, frequency control is conducted; eighthly, voltage control is conducted; ninthly, active output and reactive output are adjusted, and the offset is adjusted; tenthly, a new round of load flow calculation is prepared. According to the active power distribution network control strategy and method, global optimization can be achieved only with the communication of local information, the control efficiency is improved, and the control cost is reduced; due to the layered control over an active power distribution network, the logic and the function of protection can be verified more comprehensively, more efficiently and faster, the functions of control and protection are fully developed, the safe and reliable operation of a power grid is ensured, the debugging manpower and the debugging material resources are greatly saved, the production cost is lowered, and industrialization, application and popularization in the future are facilitated.
