Embodiment Construction

[0063] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0064] The method process of the present invention is as Figure 7 shown.

[0065] 1. Combining the geographical conditions and site restrictions of the optimized area, determine the type of distributed power source used in the area and the upper limit of the capacity of the distributed power source used.

[0066] 2. Conduct research on the optimized area, including collecting load data and meteorological data (light, temperature and wind speed data) in the area, grasp the load demand in the area, model the output of photovoltaics and wind turbines based on the meteorological data, and optimize the entire optimization process. The results have significant value.

[0067] In practical engineering applications, the output power of the photovoltaic array can use the following empirical formula, which uses the method of comparing with the ligh...

Abstract

The invention discloses a high-fitness interactive microgrid configuration method which is adaptive to various requirements including operation condition requirements, voltage loss requirements and distributed electrical connection requirements. According to the method, various distributed generators are fully considered, restriction is made before configuration according to the geographical conditions, wind and light conditions and operation site conditions of various regions, so that the configuration result has optimization meaning and application value. The optimization target is that the overall cost of a microgrid is minimum, and the life-cycle cost of the distributed generators, the cost of power distribution networks and benefits of the microgrid are also taken into account. The configuration method is based on the improved genetic algorithm, global searching ability is improved, and complicated power supply optimizing configuration can be achieved.

Description

technical field [0001] The invention relates to a high adaptability interactive micro-grid power supply optimization configuration method, which belongs to the technical field of power supply optimization configuration. Background technique [0002] With the global energy crisis, low-carbon, clean renewable energy has become a research hotspot. At present, countries around the world are carrying out research projects on micro-grids containing renewable energy. my country has also successively carried out micro-grid demonstration projects, and the planning of distributed power sources in micro-grids has also become an important research issue. [0003] Distributed power sources, especially renewable energy sources, are intermittent and uncontrollable, and access to the power grid will have an impact on the power system, which needs to be limited. In the current microgrid planning project, there is planning based on empirical values, and the actual use is far from the expecte...
