Abstract

Disclosed is a wind power, photovoltaic, photo-thermal and medium heat storage combined energy supply system. Original 'abandoned light' 'abandoned wind' energy can be stored in a heat mode through medium energy storage temporarily. Heat is released during the peak of the power grid to generate power, and accordingly, a power grid peak adjusting effect is provided, and waste of energy can be well prevented. By medium energy storage, unstable photovoltaic electric energy can be converted into stable heat energy to be output during large fluctuation of wind and photovoltaic power generation, and accordingly, the stable supply of energy can be guaranteed effectively, and impact on the power grid is reduced. A second heater can be used for heating low-temperature media output by a low-temperature medium tank, or a third heater can be used for heating water in a heat exchanger, and accordingly, the medium energy storage or heat exchanger heating efficiency is improved, the generating capacity is improved, a steam generator set can perform instant power generation supply or release heat during the peak of the power grid to generate power, and the power grid peak adjustment function is perfected.

Description

technical field [0001] The invention relates to the field of power generation, in particular to a combined energy supply system of wind power, photovoltaic, photothermal and medium heat storage. Background technique [0002] my country's wind power and photovoltaic power generation-based new energy has made great progress in recent years. As of the end of 2014, my country's installed wind power capacity has reached 91.7446 million kilowatts, and photovoltaic installed capacity has reached 14.79 million kilowatts, both ranking first in the world. However, due to the fact that in the process of new energy construction, the main focus is on resources while ignoring the market, resulting in excess scale, which makes it difficult to send out power generation, and the phenomenon of "abandoning wind" and "abandoning light" appears. [0003] In the first half of 2014, the new grid-connected capacity of wind power in the country was 5.84 million kilowatts, an increase of about 21% ye...
