Optimal Scheduling of Power System With New Energy High Penetration and Deep Peak Regulation of Thermal Power Units
In order to solve the problem of abandoning wind and photovoltaic power under a high proportion of new energy integration,an optimal model of a power system with new energy consumption and deep peak regulation is established.The optimization objective of this model is the smallest system operating cost,including the operation cost of thermal power units,compensation of deep peak regulation of thermal power unit,operation cost of wind-photovoltaic-energy storage,and penalty cost of abandoned wind and photovoltaic power.CPLEX solver is utilized to obtain the optimal scheduling model of a power system with five thermal power units,one wind farm,one photovoltaic plant,and one energy storage power station.The peak regulation of energy storage and thermal power units is analyzed.The results show that the high proportion of new energy integration easily leads to the phenomenon of abandoned wind and photovoltaic power,but the energy storage power station can decrease the ratio of abandoned wind and photovoltaic power and reduce the system operating cost.However,relying solely on energy storage for peak shaving can easily increase the construction cost of energy storage power stations.Deep peak regulation of thermal power units can reduce the capacity of energy storage configuration and improve new energy consumption.Greater depth of peak shaving leads to a lower ratio of abandoned wind and photovoltaic power and the system operating cost.
