Efficient power system load dispatch has become a new way to solve the balance between power supply and demand,It is of great significance for reducing enterprise costs.By analyzing the power situation in the western Mongolian region,two scheduling goals of low pollution emissions and low-cost power generation are determined,and a power load scheduling model is constructed.At the same time,a multi group collaborative particle swarm optimization model is introduced to solve the power load dispatch model,and a collaborative strategy is used to handle multiple objective problems in different groups to avoid the model falling into local opti-ma.In the forefront comparison,the proposed model has improved performance by 18.65%and 12.65%compared to multi-objective evolution and multi-objective particle swarm optimization.In the power system scheduling test,the optimal generation cost of the pro-posed model is 30.413 3 × 104 yuan,with an optimal pollution discharge of 1.859 2 yuan × 1041b.Compared to the other two models in terms of power generation costs and pollution emissions,there are significant advantages.From this,it can be seen that the pro-posed technology has better application effects,and the research technology provides technical reference for the optimization of power grid scheduling and energy conservation and emission reduction.
