33节点配电网潮流分区matlab程序

以下是一个简单的33节点配电网潮流分区的Matlab程序示例。程序基于Matpower电力系统仿真软件包，需要先安装Matpower才能运行。

% Load the IEEE 33-bus test case
mpc = loadcase('case33bw');

% Define the reference bus
ref_bus = 33;

% Define the slack bus
slack_bus = 1;

% Set options for the power flow calculation
opt = mpoption('PF_ALG', 1, 'VERBOSE', 0);

% Run the power flow calculation
results = runpf(mpc, opt);

% Calculate the bus voltage magnitudes and angles
V = results.bus(:, VM) .* exp(1j * pi/180 * results.bus(:, VA));

% Calculate the complex power injections
S = (results.bus(:, PD) + 1j * results.bus(:, QD)) / mpc.baseMVA;

% Calculate the complex power flows on the lines
F = (results.branch(:, PF) + 1j * results.branch(:, QF)) / mpc.baseMVA;

% Define the load zones
zone1 = [1:4, 6:8, 10, 13, 14, 17:19, 22, 23, 26:28, 30, 31];
zone2 = [5, 9, 11, 12, 15, 16, 20, 21, 24, 25, 29, 32, 33];

% Calculate the load zone injections
S1 = sum(S(zone1));
S2 = sum(S(zone2));

% Calculate the line flows between the zones
F12 = sum(F(zone1, zone2));
F21 = sum(F(zone2, zone1));

% Print the results
fprintf('Load Zone 1 Power Injection: %.2f + %.2fj MW\n', real(S1), imag(S1));
fprintf('Load Zone 2 Power Injection: %.2f + %.2fj MW\n', real(S2), imag(S2));
fprintf('Power Flow from Zone 1 to Zone 2: %.2f + %.2fj MW\n', real(F12), imag(F12));
fprintf('Power Flow from Zone 2 to Zone 1: %.2f + %.2fj MW\n', real(F21), imag(F21));

该程序将33节点配电网分为两个负载区域，并计算每个负载区域的功率注入和区域之间的功率流量。可以根据需要修改程序以适应不同的系统和分区。
