Embodiment 1

[0053] The distribution network planning method with photovoltaic power source described in the present invention mainly includes the annual investment and operation cost of photovoltaic power source, the annual loss cost of the network, the electricity purchase cost to the upper power grid and the social cost saved by the photovoltaic power source due to policy subsidies, including the following steps :

[0054] (1) Establish the objective function of social cost:

[0055] minC t o t a l = C p + C l o s s + C e n - C P U

[0056] In the formula, C total is the social cost; C p is t...

Abstract

The invention relates to the technical field of power distribution networks, in particular to a method for planning a power distribution network comprising photovoltaic power supply. The method comprises the following steps: (1) establishing a target function of social cost; (2) determining a constraint condition; and (3) determining the planning method with a particle swarm algorithm containing chaos optimization, outputting the optimal planning scheme and determining the optimal access position and capacity of the photovoltaic power supply. According to the method, the optimal access position and capacity of the photovoltaic power supply are calculated, so that the network loss of the power distribution network is reduced; the operating cost of the power distribution network is reduced; the voltage of a system is improved; the load capacity of the system is enhanced; safe and effective operation of the power distribution network can be ensured; and the economic benefits can also be further improved.

Description

technical field [0001] The invention relates to the technical field of distribution networks, in particular to a distribution network planning method including photovoltaic power sources. Background technique [0002] With the reform of the power market and the continuous development of technology, photovoltaic power generation systems have developed on a large scale. This new form of power generation supports the operation of the existing distribution network to a large extent. Small photovoltaic power stations can be installed near users by using idle spaces such as roofs. Large photovoltaic power stations require independent sites and can be installed independently. The output of electric energy is safe and flexible; with its advantages of cleanliness and environmental protection, it has been strongly supported by national policies. [0003] With the continuous development and progress of technology, the future grid needs to consider accepting more photovoltaic power sou...
