The invention relates to an improved direct energy balance load coordination control method and system. The method comprises the steps that a boiler energy requirement index BD serves as a set value of a PID controller, a heat signal serves as a controlled variable of the PID controller, a combustion amount instruction is changed through the proportion of deviation of the set value and the controlled variable and the integral action, and meanwhile a new feedforward instruction is used for adjusting the coal combustion amount instruction, wherein the new feedforward instruction comprises a load instruction function, an intelligent overshooting unit and a steam pressure deviation and coal amount correcting function. Compared with the prior art, the improved direct energy balance load coordination control method and system have the advantages that the variable load coordination capability of a coal-fired unit is increased integrally, and stable control over main steam pressure is also facilitated.
