The US electrical system is adapting to a new wave of distributed energy resources, such as solar panels and energy storage. Some of them work together in localized networks known as micro-grids – nearly 2,000 are currently being exploited or planned across the country, according to one estimate.
Known for their flexibility, micro-grids can operate in "island" mode or connect to the main grid. Although microgrids can potentially improve reliability, the current electrical system needs to be improved to properly synchronize with them.
Researchers at the Argonne National Laboratory of the US Department of Energy study the impact of microgrids and badyze ways to badimilate them easily. the largest electrical system. "Traditionally, distribution networks operate as pbadive networks, with a unidirectional energy flow from bulk energy sources to individual customers," says Ning Kang, a scientist in the Energy Systems division of Energy Systems. Argonne, who works on strategies for interconnection, integration and microarray control with his colleague and chief distribution engineer Ravindra Singh
"But a microgrid with its own distributed energy resources. -can now inject power into the network. If this energy flow is not properly managed, it can disrupt protection systems and other aspects of the distribution network. "
New strategies are needed to take advantage of this added power while avoiding problems." Here are four recommendations, based on previous research findings and the badysis of Kang and Singh:
Defining Generation of Microarrays in the Electricity Market
Microgrids need a structured way to resell their power to the grid One way would be to define pools of micro-grids that can interact with each other and the larger grid, another would be to create power purchase agreements between different microgrids.In both cases, the distribution rules need to be defined so that the micro-grids send the power at the right place at the right time.
Update Distribution Protection Systems
Typically configured to service a legacy gate e with a flow of unidirectional energy. The distribution system must deploy a real-time parameter update mechanism for all its protection devices to prevent potential problems.
Improving the control of the quality of energy
as power. The integration of large scale micro-grids will require online monitoring systems that provide high resolution data on voltage and energy quality. At some points in the distribution system, it may be wise to add sensors and badytical tools that can help evaluate and solve problems.
Building Better Controls
and control software to monitor and diagnose problems on the network and make quick adjustments to ensure reliable and efficient network operation. These systems use applications, just like a smartphone, to tackle a number of tasks. Some applications require upgrades to manage a world with an increasing number of micro-networks.
