The main purpose of this paper is to propose a correlation index between average time diagram of Photovoltaic Power Plant production and a typical diagram of the price of electrical energy at the open market. The basic idea is to define correlation index, which is of key importance for assessing the economy of a Photovoltaic Power Plant under open market conditions. This index may be useful for investors during evaluation of economic parameters of a Photovoltaic Power Plant project which will one part of its lifetime operate at the open market. In this paper, a case study for the project Bavaniste - Serbia is been presented. The estimated value of correlation index shows that each of the produced MWh at prospective Photovoltaic Power Plant Bavaniste will realize a price at The Germain Electricity Market - EEX, which is on average 20.8% higher than the average annual price of an MWh. By taking example of the prospective Photovoltaic Power Plant located in Bavaniste in Serbia, the proposed methodology has been used to show that the average MWh of electrical energy produced by a Photovoltaic Power Plant at the open market, can be over 20% better valued compare to Wind Power Plant in the same region.

Energy Conversion System

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.

The Future

The future of European energy is moving towards a single European electricity market and an increasing share of renewables in the overall production mix. After the expiration of governmental incentive measures, power plants based on renewable energy sources will enter the liberalized market, where electricity prices will largely depend on the production of renewable energy sources. In order to achieve the maximum possible profit of the power plant under such conditions, it is necessary to consider the possibility of investing in solutions that are less represented today, but with the prospect of being more profitable in the future. Such a solution is a solar power plant consisting of vertically placed bifacial modules whose active surfaces are oriented in the east-west direction. This configuration of the power plant can achieve higher production in periods of high prices, and thus higher profits from the sale of electricity. On the other hand, such a solution is more expensive than a standard solar power plant with monofacial modules. In this paper, a comparison of return on investment in a bifacial power plant and a monofacial power plant with existing and prospective market conditions is performed. PVsyst software was used to analyze the solar potential and production profiles of photovoltaic power plants. The influence of solar power plant production on the price of electricity was investigated on the example of Germany. Based on this research, a prognostic model of the daily price diagram on the unified European market until 2040 was formed which served for the analysis of the profitability of investments in the two considered variants of the solar power plant realization.
