초록

Since decades, the distributed energies have paid attention to the world-wide to correspond a varietyproblems caused by the global climate changes. However, the more distributed energies such as photovoltaic and windpower are extended, the more problems are raised such as power network stability and power curtailments. In recent,virtual power plant (VPP) and sector coupling are considered alternative solutions to reduce such problems. An energysystem integration is the coordinated planning and operation of the energy system as a whole, across multiple energycarriers, infrastructures and consumption sectors. In short, energy system integration is a wider range than sectorcoupling. An energy system integration concept pays attention to not only paid to different ways to produce energy but alsoto the different types of energy demand. Thus, it is important to integrate variety of energies such as electrics andnon-electrics. This paper proposes the a novel methodology of operation status regardless of the energy types. Theproposed scheme is based on the developed State of Energy (SoE) and enables energy distributions to VPP requestedcommend that is to minimize the fluctuation of renewable energies and non-controllable loads. The proposed schemeis verified its performance in the PSCAD/EMTDC environments. The simulation shows that the proposed scheme can befeasible and justifiable not only to mitigate the power system stability and power curtailment but also to apply differentsystem configurations.
