Multi-time Scale Dispatching Method of Thermal Power Units Considering New Energy Consumption
In the working process of thermal power units,affected by the evaluation method of new energy consumption capaci-ty,the proportion of new energy consumption of units after dispatching is lower.Therefore,a multi-time scale dispatching method of thermal power units considering new energy consumption is proposed.This paper deeply analyzes the demand re-sponse of power users,and establishes a dispatching model in line with the development needs of power market.Based on the probabilistic analysis algorithm,a quantitative evaluation method of new energy consumption capacity is designed to obtain the power rejection rate of new energy.Combined with the consumption evaluation results,the multi-time scale optimal dispatching strategy is designed from the two scales of day ahead and day in,and the intra-day dispatching scheme is modified in real time according to the two scales of long time and short time and the changing power of energy storage equipment.The genetic algo-rithm is combined with mutation crossover operation to obtain the optimal dispatching solution.The example analysis results show that after the application of the proposed dispatching method,the new energy consumption proportion of thermal power units has increased.
