“…The input-output characteristics of the power plant are applied on non-linear programming and non-linear approximation model. The definition of the methodology and the validation of the algorithm with the task formulation are presented in the previous articles [15,16] and in the thesis [9]. In this paper, the formulation of the optimization task estimated in two parameter areas, particularly, the limitations and the income.…”

This paper examines a stochastic approach to solving the impact of water usage rate restrictions imposed on hydro operations in order to maximize income. The hydroelectric power plant was evaluated within a stochastic control framework by taking into account operational constraints such as cash flows, water use and minimum flow rate restrictions for environmental protection. The Quasi-Newton Method of the income maximizing working mode decisions of a hydropower plant is determined for various constraints on the value of useable water. A Turkish hydropower is used for the case study; on Kura River in Ardahan city. The income is negatively affected, although not very large, for a range of restrictions the impact is not large. Numerical results point out that not to take into account environmental constraints may noticeably increase the cash-flows value of hydropower plant.

“…In [3], the authors analyze the way of minimizing the influence of the existing RES support schemes on the electricity consumers. They propose the modification of the RES support mechanisms at the legislative level that could minimize the influence of the mandatory procurement component on consumers' electricity price and could provide an opportunity for the suppliers to forecast the operation of small power plants and their generation capabilities.…”

Abstract:The integration of renewable energy sources (RES) has several complex technical and economic aspects, such as: grid reinforcement, tertiary power reserves required for intermittent operation of RES, promoting or support scheme, etc. In this paper, the focus will be given to wind and photovoltaic energy integration from the promoting scheme point of view, with a special emphasis on the case of Romania. In this respect, we propose a model that shows the relation between wind and photovoltaic energy integration and support scheme in Romania. Due to the green certificates (GC) support scheme design that is related to several elements such as total consumption forecast, installed power of the plants based on each type of RES and their full load hours that are expected to vary, we also perform several sensitivity analyses. The GC support scheme implemented in Romania provides interesting insights regarding the installed power based on the primary energy source that could benefit from the GC for RES investors, policy and decision makers.

Electric Vehicles and Vehicle–Grid Interaction in the Turkish Electricity System

et al. 2022

Electric vehicles and energy storage systems are technologies in the stage of intensive development. One of the innovative ways to use electric cars is the Vehicle to Grid (V2G) concept. V2G charging points are characterized by the ability of bidirectional energy flow while charging EV/BEV (Electric Vehicles/Battery Electric Vehicles). In periods of low energy consumption and the presence of the highest shares of renewable sources, the cleanest electricity is drawn from the grid at the lowest prices and stored in a “mobile warehouse”, which is an electric car. During the reported peaks in electricity demand and the presence of high tariffs, the previously stored energy may be sold back to the distribution network operator. Thanks to this application, the technology determines the highest profitability of the system and assigns EV/BEV the ability to manage electricity flows, while improving the energy balance of the economy. The prospects for the spread of V2G have increased along with the growing requirements for domestic economies, closely related to the significant share of renewable energy sources. The vision of connecting EV/BEV with the power grid creates completely new ways of managing energy and makes it possible to build smart agglomerations in line with the Smartcity idea. Especially since Turkey is one of the countries promoting this idea. The scientific aim of the study is to maximize the aggregator’s profits for V2G by creating a coalition with renewable energy producers and combining the capacities of many EVs and offering their total capacities to the electricity markets. The subject of the research was to obtain extensive knowledge about the vehicle–grid interactions taking place in the Turkish power system. For this purpose, an analysis is conducted to determine the optimal preferred operating points and the amount of regulation proposals that maximize the profit of the EV users while satisfying the constraints of each stochastic parameter. The results show the system benefits from the implementation of the algorithms are significant to optimal bidirectional V2G impacts on distribution systems with high penetration of EVs. The research can find practical applications in assessing the role of electric vehicles and their integration in the vehicle–grid system in power systems. At the same time, pointing to the benefits related to the implementation of such solutions for Turkey and other countries in the field of electromobility, stability of energy systems, and energy independence through the possibility of achieving the desired synergy effect.
