using JuMP
using HiGHS

定义UnitCommitmentData结构

struct UnitCommitmentData
demand::Float64
pmin::Vector{Float64}
pmax::Vector{Float64}
cfix::Vector{Float64}
cvar::Vector{Float64}
end

构建Unit Commitment模型

function build_uc_model(data::Union{String, UnitCommitmentData})
# 如果数据是文件路径，加载数据
if typeof(data) == String
# 这里假设读取数据的逻辑
# data = read_pkl_gz(data)
end

# 创建优化模型
model = Model(HiGHS.Optimizer)

# 获取数据大小
n = length(data.pmin)

# 定义决策变量
@variable(model, x[1:n], Bin)  # 二元决策变量
@variable(model, y[1:n] >= 0)  # 非负连续决策变量

# 定义目标函数
@objective(
    model,
    Min,
    sum(data.cfix[i] * x[i] + data.cvar[i] * y[i] for i in 1:n)
)

# 定义约束条件
for i in 1:n
    @constraint(model, y[i] <= data.pmax[i] * x[i])  # 最大功率约束
    @constraint(model, y[i] >= data.pmin[i] * x[i])  # 最小功率约束
end

# 定义需求约束
@constraint(model, sum(y) == data.demand)

return model

end

创建并优化模型

data = UnitCommitmentData(
demand = 100.0,
pmin = [10, 20, 30],
pmax = [50, 60, 70],
cfix = [700, 600, 500],
cvar = [1.5, 2.0, 2.5]
)

model = build_uc_model(data)
optimize!(model)

输出优化结果

println("Objective value = ", objective_value(model))
println("x = ", value.(model[:x]))
println("y = ", value.(model[:y]))
