Varying power demand with TimeSeries data & Ending a system

Dear all,
I have 2 questions please.
I'm currently building a Hybrid Power System (in Simulink & SimPowerSystems) with real world wind, and targeted building values. Both wind speed and power demand of the building is in TimeSeries format.
Unfortunately, I can't find the correct way to implement the varying load correctly. I have tried 2 methods: Using the 3-phase Dynamic Load block, and by basically subtracting the load demand from power generated (P_gen - P_demand = P_difference)
1. How do i implement a varying load demand with simulink blocks? 2. If i just basically subtract load demand from power generated, what do I end my system with? Doing this no longer allows me to end my system with a load block. So in my system with AC-DC Link-AC converter, my output from that goes no where. I'm not too sure of putting a 3-phase dynamic power supply to model a grid is what I should do as the building i chose is taken off grid.
Please help. Ping me for clarification if need be. Thank you.

Hello KahHin,
using the dynamicl load block is the correct way. Why do you say it doesn't work? Use the three phase one and select the option to specify real and reactive power externally. Then you will have a simulink line to input the power draw you want the load to pull.
