Modeling - Active Distribution Networks with PVDG

Modeling project in a group of 4 titled as ‘Forecasting of PV Generation and Load Demand at IIT Gn-VGEC Campus’ was based on a photovoltaic (PV) system installed at IITGN-VGEC campus. The project work was distributed clearly in four parts as follows:

Part – 1: Forecasting of ambient temperature and solar irradiance based on Modified ASHRAE model

Part – 2: Forecasting of PV output based on Regression Analysis

Part – 3: Forecasting of PV output based on Single Diode Equivalent model

Part – 4: Load modeling based on Regression Analysis

Part - 3: A single diode equivalent model to represent PV module was implemented by me. The model is proposed in a highly cited research paper published in IEEE transactions on Power Electronics in May 2009, [3]. The proposed model has two improvements over conventional single diode equivalent model. Confirming results have been obtained and matched with those published in the paper. Further, two generalized MATLAB functions are coded which can accept specifications for any PV module and produce I-V, P-V characteristics while determining the equivalent series (Rs) and parallel resistance (Rp) of the given module. The same model is used to forecast PV module output at different irradiance and module temperature for the PV system installed atop L-Block in IITGn-VGEC campus.

In order to integrate the whole project on one platform, a User Interface (UI) was designed in MS-EXCEL with a link to MATLAB. It integrated the four different modules prepared by each member of the group task.
