Power grid peak-load regulation control system and method considering summer air-conditioning load difference characteristics

Abstract

Disclosed are a power grid peak-load regulation control system and method considering summer air-conditioning load difference characteristics. Supply side electric power is jointly supplied by a purecondensing type thermal power generating unit and a photovoltaic power generation array; each user adopts an air-conditioning power consumption mode to supply cooling; on the basis of historical detection, energy supply and energy consumption conditions in a certain time of the further can be predicted; next, on the basis, dispatching is performed, so that the power generation output of the pure condensing type thermal power generating unit can be reduced, and joint compensation between a user refrigerating load and the photovoltaic power generation array can be realized; therefore, relative to the fluctuation properly of photovoltaic power generation, the user air-conditioning power utilization load also can be adjusted (by adjusting the user refrigerating load, consumption of the photovoltaic power generation can be promoted and power grid load pressure in the electric power peak time frame also can be lowered); and in addition, in energy compensation regulation, user self differences (different users can accept different temperature change amplitudes, and after different users close air conditioners, the indoor temperature rise rates are also different, so that the user air condition switch-off time frames are different under the premise of satisfying cooling supply comfort degree of different users) are also taken into consideration, so that effective regulation of the whole system is realized.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of new energy, and relates to a joint scheduling system and method for a pure condensing thermal power unit, a photovoltaic power generation output, and a user's air-conditioning refrigeration load. technical background [0002] Renewable energy has the characteristics of green and clean, and has developed rapidly in recent years. But taking photovoltaic power generation as an example, while photovoltaic power generation provides clean and low-carbon energy, the randomness of photovoltaics has also become a major problem in photovoltaic consumption. The related technologies are not perfect, mainly reflected in the following aspects: 1) The peak shaving depth and peak shaving speed that the existing power supply can provide for new energy consumption are not enough to meet the requirements of new energy consumption; 2) The existing user load In the system participating in power g...
