Power Flow Management for Smart Grids: Considering Renewable Energy and Demand Uncertainty

The increase in distributed energy resources using renewable energy such as photovoltaic and wind generation systems require new strategies for the operation and management of the electricity because of their intermittent nature, and is uncontrollable. The high proportion of distributed energy resources and uncertainty of power loads makes the power flow and energy management complex. Due to the uncontrollability of these power devices, the power imbalance between generation and consumption is an important issue to be solved. Hence, there is a need to develop sophisticated power flow control systems which can control power flows from distributed power sources to power loads in real-time. This paper presents the power flow control mechanism, which assigns power to controllable power sources and loads, and connections between them to absorb the power fluctuations caused by fluctuating power sources and loads.
