Embodiment Construction
[0054] In order to better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and examples.
[0055] The invention provides a capacity planning method for energy storage coordinated heat storage electric boilers to reduce abandoned wind, such as figure 1 As shown, the capacity planning method includes the following steps:
[0056] 1. Calculate the power upper limit of the continuous thermal load curve of the electricity price, the power upper limit of the continuous thermal load curve of the electricity price includes the power upper limit of the continuous thermal load curve during the peak period of electricity price and the low valley period of electricity price;
[0057] Power ceiling for continuous thermal load curves during peak electricity prices Calculate with the following formula:
[0058] P L h = m...

The invention relates to a capacity planning method for an energy-storage coordination heat-storage type electric boiler, and the method comprises the following steps: I, calculating the upper limit of the power of an electricity price continuous thermal load curve; II, calculating the heat energy of the electric boiler; III, calculating the electric energy vacancy of a thermal load during the peak period of the electricity price; IV, calculating the capacity of a device; V, calculating the power demands of an energy-storage device during the peak and valley periods of the electricity price; VI, calculating the power demands of the energy-storage device in the whole period. The method can give consideration to safety and economic performances according to the yearly wind electricity, thermal load data and peak-valley time-of-use electric price data of a to-be-planned region, achieves the power and capacity planning of the energy storage device with the maximum storage of wind electricity and minimum system comprehensive cost, and the heat-storage type electric boiler.
Description
technical field [0001] The invention relates to a capacity planning method, in particular to a capacity planning method of an energy storage coordinated heat storage electric boiler. Background technique [0002] Under the background of energy conservation, emission reduction and environmental governance, the state has issued a series of favorable policies for renewable power sources, and the installed capacity of wind power has grown rapidly. According to statistics, by the end of 2015, the cumulative installed capacity of wind power reached 145 million kilowatts. my country's wind energy resources are mainly distributed in the northeast. In North China and Northwest China, due to problems such as insufficient power grid transmission capacity, limited system peak-shaving capacity, and insufficient local load consumption capacity, wind curtailment has become an important issue that needs to be resolved for the healthy development of the wind power industry. Taking Jilin as an...
