Shenzhen being central air-conditioning energy transformation, pushing the storage technology, effective use of power to enhance peak load shifting. Shenzhen Power terminal load management mode, the use of air-conditioned storage technology evening of excess electricity is stored and then used to get during the day, this is equivalent to establish a virtual power plant. Shenzhen in the completion of construction or transformation of central air conditioning project, construction of one million kilowatts of thermal storage air conditioning virtual power plant. Refrigeration Express correspondent was informed, Shenzhen power grid last year, the maximum load of about 11.51 million kilowatts, the maximum load gap of about 700,000 kilowatts, electricity huge difference between peak and valley load and peak load shifting must be used to protect the balance of power. Market coverage is less than 1% of central air-conditioning use of storage facilities, with the economic development of the power peak and valley load differential widening, air solar power air conditioners accumulator is a trend. Rapid economic development is to make the difference of day and night electricity demand growing, the thermal unit commitment peaking a huge loss, a 125,000 kilowatts generating set start and stop time, the need to consume 20 tons of standard coal; a 200,000 kilowatts generating unit solar powered air conditioner peaking time, consumption of 34.8 tons of standard coal. Insiders pointed out that one million kilowatts of peak load to a low, use of power low power supply capacity to meet the power requirements of the construction of one million kilowatts of peak power stations, to less and less to build two 500,000 kilowatts of 500 kilobits voltammetry substation. Comprehensive investment of 10,000 yuan per kilowatt, a considerable saving of 10 billion yuan of investment costs.
