The figure below is an illustration of the optimization process:įor detailed problem formulation and case study results see here. In this lecture we will discuss about MATLAB simulink simulation of HVAC transmission system and power generation from wi. Ga_run.m - We solve the problem using a genetic algorithm solver (i.e. HVAC_opt_multiobjective.m - We formulate the objetive functions as the output of EnergyPlus simulation Problem definition: We try to optimize HVAC heating and cooling set points in office spaces with respect to energy savings and occupants' thermal comfort. Runep(filename, epwfilename) - Runs E+ process directly in Matlab given. Idfwrite(filename) - Write IDF file from structure array. Energy consumption for household HVAC systems constitutes a large demand response potential if it can be. Idfread(filename) - Reads and parses IDF file in a structure array. MLE+ provides the capa- bility to perform co-simulation with EnergyPlus from Matlab. 1 and is used to convey thermodynamic properties of moist air, such as dry-bulb temperature, web-bulb temperature, relative humidity, humidity ratio, enthalpy, and volume. It is based on the ASHRAE Psychrometric Chart No. This figure shows a psychrometric chart for the moist air inside the cabin.

Replace set program_path=%~dp0 with set program_path="%ENERGYPLUS%".Find RunEPlus batch file in E+ installation.Create IO folder in E+ installation with two subfolders "Input" and "Output".Set environment variable ENERGYPLUS and point it to the location of the E+ installed folder (e.g.A framework to couple Matlab with EnergyPlus and solve simulation-based optimization problems. For example, the BCVTB allows to simulate a building and HVAC system in EnergyPlus and the control logic in MATLAB/Simulink, while exchanging data between.
