使用 Python 优化电力系统发电量
import numpy as np from scipy.optimize import minimize
Define the cost function for power generation
def cost_function(x): # Assuming a linear cost function: C = a * P + b a = 0.1 # Cost coefficient b = 10 # Cost constant return a * x + b
Define the objective function to be minimized
def objective_function(x): return np.sum(cost_function(x))
Define the power demand constraint
def demand_constraint(x): return np.sum(x) - demand
Define the power generation limit constraint
def limit_constraint(x): return max(x) - max_generation
Define the system constraints
constraints = [ {'type': 'eq', 'fun': demand_constraint}, {'type': 'ineq', 'fun': limit_constraint} ]
Define the initial guess for power generation
x0 = np.array([0.0])
Define the power demand and maximum power generation
demand = 100.0 max_generation = 150.0
Solve the optimization problem
solution = minimize(objective_function, x0, constraints=constraints) x_optimal = solution.x
Print the optimal power generation and total cost
print("Optimal power generation:", x_optimal[0]) print("Total cost of power generation:", objective_function(x_optimal))
