Adaptive wind, air, solar thermal energy optimization system and control method

Abstract

The invention relates to an adaptive wind-air-light-heat energy optimization system and control method, and belongs to the field of building energy supply. The invention mainly aims at solving problems that the conventional energy-saving technology is not ideal and is not good in adaptability. The system comprises a wind power generator set, a photovoltaic power generator set, an electric heating water storage and energy storage device, a solar energy collector, an air source heat pump set, a control system, an energy acceptor system, and a building power supply system. The control method carries out the adjustment of indoor temperature, power generation and heat storage. The adjustment of indoor temperature is carried out through collecting the indoor and outdoor temperatures and judging the starting of a heat supply system or a cooling system; The adjustment of a power generation system is carried out through the following steps: collecting the weather condition of a geographic position where a building is located, judging the user type of the building, judging whether time is a peak moment or not, and carrying out power storage or power supply. The adjustment of a heat storage system is carried out through the following steps: collecting the pressure value and temperature value of the heat storage system, comparing the pressure value and the temperature value with set values, and controlling the starting of the heat storage system, the air source heat pump set, or the hot water system according to a comparison result.

Description

technical field [0001] The invention relates to the field of building energy supply, in particular to an intelligent energy supply system that optimizes the combination of multiple renewable energy sources. Background technique [0002] At present, the total energy consumption of buildings in my country is increasing year by year, and its proportion in the total energy consumption has risen from 10% in the late 1970s to 27.45%, gradually approaching 30%. Energy consumption generally accounts for about 33% of the country's total energy consumption. Research by the Science and Technology Department of the Ministry of Construction shows that with the acceleration of urbanization and the improvement of people's quality of life, the proportion of my country's building energy consumption will eventually rise to about 35%. With such a large proportion, building energy consumption has become the weakness of my country's economic development. [0003] Until the end of 2002, my count...
