Abstract: To solve the problem of wind power accommodation, this paper proposed a coordinated wind power accommodating dispatch model based on electrical boiler（EB） and cogeneration units with thermal energy storage（TES）, with the perspective of decoupling thermoelectric coupling constraints and enhancing the adjustment capacity of the power system. This paper analyzed the principle of cogeneration units with TES, and presented the calculation method of the ultimate wind power accommodated heating capacity of the EB. Then the economy had been compared considering the TES work alone or does not work, as well as the two heating units work coordinately. Example results show that the best economy could be achieved when the EB heating capacity reached the ultimate wind power accommodated heating capacity.
