This paper documents the effect that the PI controller gains in the generic WECC photovoltaic power plant have on the system modes.

Today, the operation of sustainable power plants mainly relies on visualization of power production. Measurement data of such power plants are often discarded. We show the idle potential of such data by applying a state of the art algorithm to recognize malfunctions in a photovoltaic power plant. Up to now, these failures could only be found by manual inspection of the power plant every six wee...

The Kerman Photovoltaic Power Plant is unique, not in the particular photovoltaic equipment selected, but in the siting of the plant in relation to the electric power system and how the plant interacts with that system. Kerman is the world’s first plant designed and built specifically to measure the benefits of a photovoltaic system to the local distribution grid. In addition to the traditional...

We present the development of a dynamic software simulation environment for modelling small and large scale photovoltaic (PV) energy generation systems. The model elements of solar panels, Maximum Power Point Trackers (MPPT) and solar inverters were integrated to a simulator system providing weather and power grid models as well as simulation of combustion power plants. The integrated system en...

Since the penetration of photovoltaic systems in the electrical network is increasing, the need to register and model the contribution of these energy sources, in terms of generated disturbances, quality and amount of available power, is becoming a crucial issue for optimal management of grid. So, this paper, starting from data experimentally recorded on a medium scale photovoltaic system that ...

Global warming is a direct consequence of consumption of fossil fuels which emit greenhouse gasses as they produce energy. Solar energy is the most available energy throughout the world in which regardless of capital investment is free and most importantly clean and emission free and could be a solution for global warming along with other renewable sources of energy. But as photovoltaic energy ...

Photovoltaic Power Plants (PVPP) are classified as a power energy sources with non-stabile supply of electric energy. It is necessary to back up power energy from PVPP for stabile electric network operation. We can set an optimal value of back up power energy with using variety of prediction models and methods for PVPP Power output prediction. Fuzzy classifiers and fuzzy rules can be informally...

The main objective of this paper is to evaluate the stability of a grid for a NonConventional energy generating system that is photovoltaic power plant t h a t features a maximum power point tracking (MPPT) scheme based on fuzzy logic control. The step of modeling with MATLAB/Simulink of the photovoltaic system is shown respectively and simulation results are discussed. This fuzzy MPPT shows ac...

The utilization of renewable energy sources in electric power systems is increasing quickly because of public apprehensions for unpleasant environmental impacts and increase in the energy costs involved with the use of conventional energy sources. Despite the application of these energy sources can considerably diminish the system fuel costs, they can also have significant influence on the syst...

Batteries and fuel cells contain a great potential to back up severe photovoltaic power fluctuations under inclement weather conditions. In this paper comparison between batteries and fuel cells is carried out in detail only for their PV power backup options, so their common attributes and different attributes is discussed. Then, the common and different attributes are compared; accordingly, th...
