The method of claim 16, wherein the first group comprises some but not all MGCs in the first microgrid, and wherein the second group comprises some but not all MGCs in the first and second microgrids.Ģ0. The method of claim 16, wherein the first group comprises every MGC in the first microgrid, and wherein the second group comprises every MGC in both the first and the second microgrids.ġ9. The method of claim 16, wherein the method comprises operating a decentralized microgrid control system without use of a control central unit.ġ8. A method of operating a microgrid control system to control a microgrid arrangement comprising a first microgrid and a second microgrid separated by a microgrid breaker, the first and second microgrids each comprising a plurality of assets, each asset being associated with a respective microgrid controller (MGC) of the microgrid control system, the method comprising: determining that the microgrid breaker is open based on the determination that the microgrid breaker is open, for at least one MGC of the MGCs in the first microgrid, assigning the MGC to a first group of MGCs in the first microgrid broadcasting information from the MGC to other MGCs in the first group determining that the microgrid breaker is closed based on the determination that the microgrid breaker is closed, assigning the MGC to a second group of MGCs in both the first microgrid and the second microgrid and broadcasting information from the MGC to MGCs in the second group.ġ7. Here the BESS is a critical part of the VPP infrastructure, providing grid stability by balancing the intermittent generation with smart and dynamic loads.16. This concept enables electricity produced from DERs, even at the consumer level, to be integrated intelligently, simulating a utility-scale power system. This foundation allows new concepts, like VPP become reality. The real key to stabilizing grids and unlocking new revenue streams comes from the integrated, intelligent software with digital capabilities. “What is exciting is that the BESS can give us new ways to orchestrate, optimize, and manage our existing infrastructure, as well as a path to the future, especially with more renewable power and the expected increase in electrification across many industries.”Īt the core, the e-mesh software platform and BESS connect with various power sources to provide uninterrupted and high-quality power. “We know there are many complexities at play in today’s energy market and have worked with Hitachi Energy for a long time as a valued partner,” said René Soland, Head of Business Unit Grids and member of the Management Team of AEW Energie AG. Longer term, there are plans to identify capabilities that can address new market opportunities, including managing EVs within their grid, virtual power plants (VPPs), and energy trading. They plan to initially use the BESS with a capacity of 5.5 MW/10MWh as a learning platform to enhance grid stability and add more distributed energy resources (DERs) to their operations. Known as the e-mesh portfolio, the combined solution provides AEW with a BESS, advanced analytics, software, and digital capabilities to both meet the needs of today and what is ahead tomorrow.ĪEW is first taking an exploratory approach. In looking at new ways to enhance the energy network, AEW recently added a battery energy storage system (BESS), with intelligent automation software from Hitachi Energy. The common challenge across all stakeholders is how to adapt to this new decentralized model, while delivering energy securely and sustainably. To support the range of future energy needs while meeting sustainability and reliability targets requires ingenuity and strong partnerships.ĪEW’s story is representative of larger shifts in energy, where power generation infrastructure is decentralized, consumers are becoming prosumers, and the grid system is asked to do more than it ever has before. This network is digitally advanced and designed for maximum security, while always operating with high availability. The energy network AEW manages includes both homes and energy-intensive industry. In electricity production, AEW harnesses hydropower from local sources, as well as solar and wind energy. With the goals of delivering secure and climate-friendly energy, AEW is committed to making a difference by protecting the natural resources and enhancing quality of life in the region.Įven as new concerns like energy availability and cybersecurity come in to play, AEW is searching for a multi-faceted approach to meet its goals. AEW Energie AG, an independent electricity company for the north Swiss canton of Aargau, is looking for ways to meet its net zero climate neutrality goals by 2040.
