I want to implement a switch which will open or close based on some conditions. Kindly suggest how can I achieve this?

I have designed two PV system. Second PV will remain disconnected via a switch if first PV can supply the load demand. Second PV will get connected if more power is needed to meet the demand. Now I need to implement a switch which will connect or disconnect based on these conditions.

Hi @Optimus

I think the switch action can be mathematically described by

,

with the state '0' means disconnect, and '1' means 'connect'.

D = 0.5;                    % demand
P = linspace(0, 1, 10001);  % power
S = 1 - heaviside(P - D);   % switch

plot(P, S, 'linewidth', 2), grid on, ylim([-0.5 1.5])
xlabel('Power')
xline(D, '-.', {'Demand'})
