This paper deals with the investigation and economic evaluation of power supply systems in residential buildings with different shares of renewable energy in different years, different regulatory boundary conditions and cost digression estimations. A linear programming approach is selected for the determination of technical and economical capabilities of this energy system. By investigating and simulating...
The aim of the paper is maximization the consumption of energy generated by RES in distribution system. It is achieved by aggregation of loads and power generating units to common internal grid called power park. In order to maximize consumption of renewable energy, the RES sizing optimization model is used. In order to reflect the intermittency of renewables, they are modelled by generation profiles...
We consider a microgrid with random load realization, stochastic renewable energy production, and an energy storage unit. The grid controller provides the total net load trajectory that the microgrid should present to the main grid and the microgrid must impose load shedding and renewable energy curtailment if necessary to meet that net load trajectory. The microgrid controller seeks to operate the...
This paper proposes a stochastic multiobjective framework for daily volt/var control (VVC), including hydroturbine, fuel cell, wind turbine, and photovoltaic powerplants. The multiple objectives of the VVC problem to be minimized are the electrical energy losses, voltage deviations, total electrical energy costs, and total emissions of renewable energy sources and grid. For this purpose, the uncertainty...
Distribution systems (DS) are a focal connection point for existing and new renewable energy sources. DS have increasing sizes; they connect increasing numbers of renewable energy sources and have a mandate to operate as financial entities seeking to maximize their profits in an electricity market. To achieve these goals, DS require highly efficient planning tools. In this paper, we propose a successive...
The integration of renewable energy sources such as wind power into power systems is quite difficult due to their stochastic nature. As wind power penetration begins to reach significant levels these difficulties can mean great financial expenses and increased carbon emissions. In this paper we demonstrate that through smart utilization of multiple generation sources, a technique we call integrated...
