In this study, a simulation model of in-grid solar-to-electrical energy conversion system is presented. In this case, the in-grid solar-to-electrical energy conversion system is small photovoltaic power plant, which was constructed by the Center for Renewable Energy and Power Quality from Faculty of Technical Sciences (FTS). Equivalent circuit diagram of photovoltaic cell is described which was used to develop the simulation model of modules. Possible types and topologies of inverters are also described. The photovoltaic power plant is described briefly, because it is necessary to understand the simulation model. The result of simulation is an electricity annual production by the power plant. These results were compared with the real values, while its get a good overlap. The paper also presents the modern modeling methods developed at Faculty of Technical Sciences in the Laboratory for RES systems.

Continuous Power

An AC-linked large scale wind/photovoltaic (PV)/energy storage (ES) hybrid energy conversion system for grid-connected application was proposed in this paper. Wind energy conversion system (WECS) and PV generation system are the primary power sources of the hybrid system. The ES system, including battery and fuel cell (FC), is used as a backup and a power regulation unit to ensure continuous power supply and to take care of the intermittent nature of wind and photovoltaic resources. Static synchronous compensator (STATCOM) is employed to support the AC-linked bus voltage and improve low voltage ride through (LVRT) capability of the proposed system. An overall power coordinated control strategy is designed to manage real-power and reactive-power flows among the different energy sources, the storage unit, and the STATCOM system in the hybrid system. A simulation case study carried out on Western System Coordinating Council (WSCC) 3-machine 9-bus test system for the large scale hybrid energy conversion system has been developed using the DIgSILENT/Power Factory software platform. The hybrid system performance under different scenarios has been verified by simulation studies using practical load demand profiles and real weather data.

Energy Conversion System

A nonlinear control of a PV Energy Conversion System (PVECS) with energy storage system and maximum power extraction is presented. The control strategy is designed in two steps. Firstly, a MPPT algorithm is designed to tracking the maximum power point in variable irradiations, battery state of charge (SOC) and load changes. Then, thanks to its many advantages such as simplicity against parameter uncertainties, a Sliding Mode Control approach (SMC) is applied to control the standalone PV energy conversion system. Finally, the performances of MPPT techniques and SMC controller in the closed loop are checked using the MATLAB/SIMULINK.

Energy Conversion System

Electrical energy demand increases day-by-day due to economic growth, technology development and increasing world population. The wind is one of the accessible renewable energy sources to generate electrical energy to meet the increased load demand. When the wind energy conversion system (WECS) is operating as isolated mode, it is more reliable, economical and easy to electrify rural areas. When the WECS is connected to load without controller the output three-phase voltages of the inverter have more transient and steady state errors and higher total harmonic distortion in the voltages and currents. This paper discusses various voltage controllers used in WECS in detail. The proposed WECS is simulated using MATLAB/Simulink with and without adaptive voltage controller for balanced and unbalanced non-linear load conditions. In each case the results have been analyzed and total harmonic distortion is evaluated..
