A clean combined heat and power system with off-grid optical storage and its operating method

Abstract

The invention discloses a clean heat and power cogeneration system integrating off-grid light storage and its operating method. The system includes a photovoltaic power generation system, a photothermal Energy and energy release unit, heat exchanger and throttle valve, etc., all components are connected through pipelines, heat pump unit is connected with photovoltaic power generation system, photothermal panel, hot water storage tank, deep buried pipe system, internal combustion unit and energy release unit, The other end is connected to the user side; the invention couples the solar panel and the heat pump unit, and is equipped with a deep buried pipe system, an internal combustion engine generator set, and an energy storage and energy release unit to rationally utilize solar energy and geothermal energy, so as to provide long-term and stable energy consumption during operation. Provide heat for the user side. When heating is not needed, solar panels can also be used for photovoltaic power generation. The supporting energy storage unit can solve the intermittent problem of photovoltaic power generation. It is suitable for off-grid regional heating and power supply in severe cold areas on the plateau, without pollution emissions.

Description

technical field [0001] The invention relates to the technical field of renewable energy, energy storage and off-grid power supply and heating, in particular to an off-grid optical-storage-integrated clean cogeneration system and an operation method thereof. Background technique [0002] The heating capacity of the air source heat pump system decreases rapidly with the decrease of the ambient temperature, especially when the temperature is low, the low start-up temperature will cause the system to report an error or even fail to start. The current solar heat pump system mostly uses solar photovoltaic panels to power the heat pump, which does not help the performance of the heat pump. At the same time, these solar heat pump systems have high cost, unstable operation, and low outdoor temperature in winter, making operation and maintenance difficult. [0003] In plateau alpine areas and remote mountainous areas, these areas require less energy supply, are far away from the grid...

Problems solved by technology

However, it is difficult to get rid of the dependence on the power grid. At the same time, the night temperature in the western region is extremely low and there is no sunlight, and it is difficult to use solar energy to provide heat effectively. How to solve the uncertainty of solar energy has become a key issue.
