Problems solved by technology

However, the active distribution network is still in the development stage, and there are still some theoretical and technical problems to be solved, such as planning and optimization.
[0005] In summary, considering that the current active distribution network planning method is not perfect, a new active distribution network planning method is needed to solve the above problems

Abstract

The invention provides an active distribution network planning method based on the total life cycle cost. The method comprises the steps that the active power of a DG is set; active management of on-load voltage regulation of a transformer is conducted; active management of a reactive power compensator is conducted to keep the reactive power of a distribution network to be in a given range; load modeling is conducted, and constraint formulas of the voltage, the active power and the reactive power are defined; target functions including the investment cost of the DG, the maintenance and operation cost of the DG, the electricity price cost needed when electricity is purchased from an electricity selling company, the cost of active power consumption, the expected value of the active power and the cost of active management equipment are determined; and finally a total cost function is solved. Meanwhile, the method based on the total life cycling cost is adopted in planning, and the operation cost of the active distribution network is effectively calculated.

Description

technical field [0001] The invention relates to a distribution network of a power system, in particular to an active distribution network planning method based on full life cycle cost. Background technique [0002] As an important part of the power system, the distribution network undertakes the task of safely, stably and reliably delivering power to end users, and is an important guarantee for the stable and safe operation of the power system. The two ends of the distribution network are respectively connected to the transmission network and user terminals. Its safety, stability, and reliability are directly related to the safety and reliability of industrial, commercial, and residential electricity consumption. The quality is directly related to the economy of the entire grid operation, and also affects the safety of users' electricity consumption. It can be seen that the distribution network plays a pivotal role in the power system. At present, from the perspective of th...
