The invention relates to a distribution-type household photovoltaic and
ice storage optimizing coordinated
control system and method. A photovoltaic and
ice storage air-conditioning
system stores
solar energy in the mode of ice in the
daytime, photovoltaic collecting of multiple low-energy densities is achieved, and
cooling capacity is released at night. According to the characteristics of
big data and historical data, the current
ice storage quantity and the working mode of the
system are determined through judgment of the
control system, and the
refrigeration requirements of users at night are met. Through the
operation mode of the photovoltaic and ice storage air-conditioning
system, the problem that at present, grid
electricity supply is difficult due to the large
air conditioning loadproportion is solved, and meanwhile the photovoltaic use ratio is increased; the ice is stored in the
electricity using low ebb period of the
daytime when residents go out, the
cooling capacity is released in the
electricity using peak at night, thus
peak load shifting is achieved, the electricity using peak-ebb difference is decreased, the electricity using load on the grid side tends to be stable, and the generating efficiency of a
generating unit is improved; and in addition, the
solar energy in the
daytime is stored and used at night, and the problem of photovoltaic inverse peak shiftingis solved.
