A static optimization method of a distribution network based on optical storage charging tower access

Abstract

The invention relates to a static optimization method of a distribution network based on photovoltaic storage charging tower access, which comprises the following steps: step 1, according to the historical data of photovoltaic system, predicting the output of photovoltaic system power generation; 2, presetting the capacity of the energy storage system and determining that the operation mode of theenergy storage system is peak clipping and valley filling; 3, establishing a charging load model of that electric vehicle according to the historical load data of the electric vehicle; 4, according to the model of the optical storage charging tower and the mathematical model of distribution network reconfiguration, establishing a distribution network reconfiguration model considering the access of the optical storage charging tower; Step 5, adopting the second-order cone programming method, converting the distribution network reconfiguration model considering the light storage charging toweraccess to obtain the distribution network second-order cone reconfiguration model under the light storage charging tower access, and solving the problem by GAMS. The invention can minimize the activepower loss in the daily operation of the distribution network and reduce the operation cost of the distribution network.

Description

technical field [0001] The invention relates to a static optimization method for a power distribution network based on the access of an optical storage charging tower, and belongs to the technical field of power distribution network operation control. Background technique [0002] With the development of the smart grid, the intelligence of the distribution network is getting higher and higher, and it has a certain degree of reliability, security and self-healing. More and more renewable energy is connected to the distribution network in the form of distributed power, which improves today's energy structure, but also brings great challenges to the operation of the distribution network, such as wind power, photovoltaic and other renewable energy It has strong uncertainty itself, so it will bring new challenges to the daily dispatching operation of the distribution network. In addition to the uncertainty of distributed power sources, the uncertainty of loads will also affect t...
