In view of the problem of benefit distribution in deep-peak regulation under high-penetration wind power

after analyzing the principles of peak-regulation resource allocation and characteristics of different power sources

a deep-peak regulation mechanism based on Kaldor improvement is proposed

in which the way to fully tap deep-peak regulation potential by benefit distribution is discussed. Taking the pure condensing unit

combined heat and power(CHP)unit and wind turbine as typical examples

the detailed unit benefit and constraints are depicted independently. The compensation and allocation items are also introduced into the objective function. Thus the deep-peak regulation mathematical model is constructed. According to the optimality conditions and principles of economics

the evolvement rules of unit benefit due to compensation and allocation are explored

and the mechanism of action of Kaldor improvement item in decision making is analyzed as well. Furtherly

to solve the model simply

an interval-based determination principle of compensation and allocation for engineering are given. Finally

simulation results validate the effectiveness of the novel mechanism and the rationality of the benefit distribution.
