Aiming at the difficulty of real-time dispatching in new power system
an intelligent dispatching balance system is constructed in this paper. In the intelligent balance mode of the system
the power deviation of connection line is automatically tracked
and the future power deviation is predicted by combining the ultra-short-term load forecast data
and the balance control of the future trend is carried out in advance by using adjustable resources. Secondly
combined with the characteristic of the transition stage from planning to power market
the peak cost function system of dispatching resources is constructed to accurately quantify the regulation ability of various resources. Finally
based on the cost function
the rolling optimization model of intraday planning is constructed with the high cost peaking resource as the marginal condition and the minimum overall regulation cost as the objective
so as to form the intraday power generation plan meeting the optimal balance mode. An example is given to demonstrate the superiority of the proposed intelligent dispatching method
which can realize the safe
economical and efficient cooperative interaction of the source network charge and storage in the new power system.
