Embodiment Construction

[0076] A heat storage type electric heating optimization operation control method for improving wind power consumption of the present invention will be further described below using the drawings and embodiments.

[0077] Combined with the Taonan Clean Heating Demonstration Project in Jilin Province (the specific technical parameters are shown in Table 1), the example analysis is carried out. The demonstration project has 9 regenerative electric boilers, β t Take 0% to 10%.

[0078] Table 1 The main technical parameters of a single electric boiler in the demonstration project

[0079]

[0080] According to the "Code for Design of Urban Heating Power Network", the recommended value of residential heating heat index is obtained, and 40W / m is taken 2 (5% network losses are included in the thermal index). From the analysis of the heating load distribution in general buildings, the heat load is the highest at night, and the heat load is lower during the day due to the increase ...

Abstract

The invention provides a heat accumulating type electric heating optimizing operation control method improving wind power absorption for solving the problems that a wind power heat supply operation manner is simple in our country, and the discarded wind power quantity cannot be flexibly and reasonably matched. The heat accumulating type electric heating optimizing operation control method improving wind power absorption is characterized by comprising the steps of the mechanism of improving wind power absorption through heat accumulating type electric heating, the evaluation index acquisition, operation of a heat accumulating type electric boiler, control analysis of the heat accumulating type electric boiler and the like. According to the operation control method, the requirement for loads of a user can be met, and more discarded wind power quantity can be absorbed; and the heat accumulating type electric heating optimizing operation control method has the advantages of being scientific and reasonable, high in adaptability, capable of fully utilizing energy more effectively, good in effect and the like.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and relates to a heat storage type electric heating optimization operation control method for improving wind power consumption. Background technique [0002] my country's "Three North" region is rich in wind energy resources, and wind power output is relatively large in winter. However, in order to ensure the heating demand of users, cogeneration units operate with "heat fixed power", and the power grid allows insufficient wind power capacity, resulting in a large number of "abandoned wind". In 2014, the national wind curtailment rate was 8%, and the annual utilization hours were 1893 hours. The "Three North" regions had more severe wind curtailment than other regions. Taking Jilin Province as an example, the curtailment rate was as high as 15%, and the annual utilization hours were 1501 hours. The use of regenerative electric heating technology can replace traditional coal-fired bo...
