Abstract In order to solve the problem of peaking difficulty caused by the increasing daily load peak-to-valley difference, it is necessary to optimize the peaking output of pumped storage units, hydro-power units and thermal power units. This paper proposes the first peaking optimization model of pumped storage and hydro-power with the smallest remaining load variance and the largest hydro-power generation. The second peaking optimization model of thermal power plant is constructed with power generation cost and output volatility. At the same time, constraints such as unit climbing, water storage, and power generation reference flow are considered. The multi-objective problem is processed by fuzzy optimization algorithm. Finally, the rationality of the proposed model is verified by simulation.
