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'})
