However, the current consumers have in fact borne the fluctuations in electricity costs and various inefficiencies in the electricity supply chain in the form of insurance costs (risk returns). If the load of these hours can be reduced or shifted, it will have a much larger long-term effect and external effect than the electricity bill of those hours.

The embodiment of the invention discloses a cooling unit control system and method for achieving demand side responses. The cooling unit control system comprises a first control unit and a second control unit, wherein the first control unit collects first energy data, processes the first energy data to generate the control component of a cooling machine unit and the control component of a cooling-machine cooling-water-flow variable frequency pump respectively, and controls the outlet cooling-water temperature of the cooling machine unit and the cooling-machine cooling-water-flow variable frequency pump according to the control components respectively; the second control unit collects second energy data, processes the second energy data to generate the control component of a cool-storage-device cooling-water-flow variable frequency pump, and controls the cool-storage-device cooling-water-flow variable frequency pump according to the control component; the cooling machine unit is used for generating cool water and providing the cool water for energy-using equipment, and a cool storage device is used for releasing cool energy when power utilization is limited. According to the embodiment in the technical scheme, it is achieved that the power of a cooling unit is adjusted according to the limiting condition of power consumption, and it is guaranteed that the system can meet different working-condition requirements, and safely and stably runs.
Description
technical field [0001] Embodiments of the present invention relate to heat supply technology, in particular to a cooling unit control system and method for realizing demand-side response. Background technique [0002] Power demand side management (Demand Side Management, DSM) refers to the adoption of effective incentives and guidance measures and appropriate operation methods under the support of government regulations and policies, and through the joint efforts of power grid companies, energy service companies, and power users to achieve scientific Management activities related to electricity consumption, electricity conservation, and orderly electricity consumption. At present, the electricity retail market generally implements a price that has nothing to do with time and cannot effectively reflect changes in capacity costs and marginal power supply costs. On the one hand, this is because both the government and the power sector traditionally believe that power users are...
