Abstract EN
In order to solve the influence of load uncertainty on hydrothermal power system operation and achieve the optimal objectives of system power generation consumption, pollutant emissions, and first-stage hydropower station storage capacity, this paper introduced CVaR method and built a multiobjective optimization model and its solving method.
In the optimization model, load demand’s actual values and deviation values are regarded as random variables, scheduling objective is redefined to meet confidence level requirement and system operation constraints and loss function constraints are taken into consideration.
To solve the proposed model, this paper linearized nonlinear constraints, applied fuzzy satisfaction, fuzzy entropy, and weighted multiobjective function theories to build a fuzzy entropy multiobjective CVaR model.
The model is a mixed integer linear programming problem.
Then, six thermal power plants and three cascade hydropower stations are taken as the hydrothermal system for numerical simulation.
The results verified that multiobjective CVaR method is applicable to solve hydrothermal scheduling problems.
It can better reflect risk level of the scheduling result.
The fuzzy entropy satisfaction degree solving algorithm can simplify solving difficulty and get the optimum operation scheduling scheme.
