Embodiment Construction

[0045] Referring to the accompanying drawings, the present invention will be further described in detail with specific embodiments.

[0046] In this embodiment, two distributed power sources, wind power and photovoltaic, are taken as examples for illustration.

[0047] The timing characteristics of the load are mainly related to the date type and meteorological factors. The date type can be divided into weekdays, weekends and holidays. For weekdays and weekends, the power load generally shows periodic changes, while for national legal holidays such as New Year’s Day , Spring Festival, May 1st, 11th, etc., the power load has a change rule that is obviously different from that of working days and weekends. Meteorological factors include temperature, humidity, wind speed, sunshine and precipitation, etc., and their influence on the time-series characteristics of load generally presents different rules as the seasons change. Such as figure 1 As shown, taking spring as an exampl...

Abstract

The invention relates to a distributed power supply planning method based on a time sequence characteristic and environmental benefit. The technical problem that an existing distributed power supply planning technology is high in cost and low in efficiency and resource utilization rate. The distributed power supply planning method based on the time sequence characteristic and environmental benefit comprises the steps of obtaining daily load data of a power distribution network and classifying daily load sequences, classifying the annual daily load sequences of each load point of the power distribution network into type A and recording the day number included by each category, determining typical daily load sequences, determining unit capacity distributed power supply typical daily output sequences, determining the distributed power supply typical daily output sequences, determining a target function to obtain an optimal scheme. The distributed power supply planning method based on the time sequence characteristic and environmental benefit can be widely applied to optimized configuration of distributed power supply resources.

Description

technical field [0001] The invention relates to a distributed power supply planning method, in particular to a distributed power supply planning method based on timing characteristics and environmental benefits. Background technique [0002] The energy crisis and increasingly serious environmental pollution have promoted the rapid development of distributed power generation technology. According to relevant statistics, before 2010, 25% to 30% of the world's cumulative new power generation capacity was distributed power generation. Distributed power is generally divided into two categories according to whether the consumed energy is renewable: one is distributed power that utilizes renewable energy, mainly including wind energy, solar energy, geothermal energy, ocean energy, etc. Distributed power sources of non-renewable energy mainly include power generation forms such as micro gas turbines, fuel cells, combustion engines, internal combustion engines, and combined heat and ...
