粒子群算法试算
说明: 粒子群算法,也称粒子群优化算法(Particle Swarm Optimization),缩写为 PSO, 是近年来发展起来的一种新的进化算法(Evolutionary Algorithm - EA)。PSO 算法属于进化算法的一种,和模拟退火算法相似,它也是从随机解出发,通过迭代寻找最优解,它也是通过适应度来评价解的品质,但它比遗传算法规则更为简单,它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作,它通过追随当前搜索到的最优值来寻找全局最优。这种算法以其实现容易、精度高、收敛快等优点引起了学术界的重视,并且在解决实际问题中展示了其优越性。粒子群算法是一种并行算法。(Particle swarm optimization (PSO), also called particle swarm optimization (Particle Swarm Optimization), is abbreviated as PSO, which is a new evolutionary algorithm (Evolutionary Algorithm EA) developed in recent years. PSO algorithm is a kind of evolutionary algorithm. It is similar to simulated annealing algorithm. It also starts from the random solution and finds the optimal solution by iteration. It also evaluates the quality of the solution through fitness, but it is simpler than the genetic algorithm rule. It does not have the crossover (Crossover) and the Mutation operation of genetic algorithm. Search for global optimum. This algorithm has attracted the attention of the academic community for its advantages of easy realization, high accuracy and fast convergence, and has shown its superiority in solving practical problems. Particle swarm optimization (PSO) is a parallel algorithm.)

用遗传算法来实现含有各种能源形式 的der单元的能量调度-061751110825864
说明: 用遗传算法来实现含有各种能源形式 的der单元的能量调度,实现经济化。含光电。风电等多种单元。 该算法中首先根据各种DER单元的模型列出了各个单元的经济成本公式,包含诸如运行成本、维护成本以及环境等各种费用。然后根据一天的负荷预测图,在不同的控制策略下进行经济调度,计算出各个单元 最佳出力,即输出功率。 目标函数就是成本最低,限制条件包括功率平衡,以及各个单元的输出限制等 "(The genetic algorithm is used to realize the energy dispatch of Der cells with various forms of energy and achieve economy.Contains photoelectricity.Wind power and many other units.The algorithm first lists the economic cost formulas of each DER unit according to the model of each DER unit, including various costs such as operation cost, maintenance cost and environment.Then, according to the one-day load forecasting chart, economic dispatch is carried out under different control strategies, and the optimal output power of each unit, that is, output power, is calculated.The objective function is the lowest cost, and the limitations include power balance and output limits for each unit.)
