“…For such cases, the use of finite state machine model is very suitable, because it enables to combine different representations of model's object dynamic operation very easily, just by defining appropriate number of states and transitions between them. Therefore a finite state machine (FSM) domain in Ptolemy II was used to create the model of DC boost converter [8]. Table II presents used parameters.…”

Photovoltaic (PV) arrays are used in many applications such as water heating, battery charging, hybrid vehicles and grid connected photovoltaic power plants. Their main disadvantage is that their output strongly depends on weather conditions, mainly on a solar irradiance and temperature, thus influencing the operation of each system they feed. Since the changes of PV production could be very fast, it is necessary to use dynamic modelling to evaluate PV system's behavior during these changes. This could be quite challenging, especially if the application is modelled and analyzed from longer-term point of view. This paper describes partial results achieved during the process of building such a model. Simulation models of PV array and DC boost converter with MPPT controller created in software Ptolemy II by using synchronous data flow and finite state machine domain will be presented and evaluated.Index Terms--Finite state machine, mathematical model, maximum power point trackers, photovoltaic systems.

This paper reports the development of a model for continuous simulation of the power flow into AC–DC hybrid microgrids operating for different generation–consumption scenarios. The proposed application was assembled using a multiple-input multiple-output model which was built using blocks containing simplified models of photovoltaic (PV) modules, wind turbines (WT), battery arrays (energy storage units, ESU), and power loads. The average power was used as the input/output variable of the blocks, allowing flexibility for easy reconfiguration of the microgrid and its control. By defining a generation profile, PV and WT were modeled considering environmental conditions and efficiency profiles of the maximum power point tracking (MPPT) algorithms. ESUs were modeled from intrinsic characteristics of the batteries, considering a constant power charge regime and using the State of Energy (SoE) approach to compute autonomy. To define a consumption profile, DC and AC loads were modeled as a constant real power. As an innovative characteristic, unidirectional and bidirectional power conversion stages were modeled using efficiency profiles, which can be obtained from experiments applied to the real converters. The outputs of the models of generation, consumption, and storage units were integrated as inputs of the mathematical expressions computing the power balance of the buses of the microgrid. The proposed model is suitable to analyze efficiency for different configurations of the same microgrid architecture, and can be extended by integrating additional elements. The model was implemented in LabVIEW software and three examples were developed to test its correct operation.
