Eloncity is not a simple project it contains a complex technical component. This can be very interesting for those who are engaged in engineering or energy. In this company there are real challenges and strong experts. I took a small piece of white paper dedicated to the technology of building blocks. I hope this will help you to understand the meaning of the whole company in more detail. But if you have any questions feel free to contact the telegram channel there is an active discussion of the project.
ECTP OPERATION
The ECTP specifies the algorithms and rules for an Eloncity microgrid operation. To implement this protocol, we will need software and hardware to conform to ECTP specifications. An ECTP-compliant microgrid operation consists of the following elements:
• Core ECTP core energy exchange platform based on high-performance blockchain network. The Eloncity blockchain will be an enhanced Ethereum blockchain technology that has been optimized for the high-volume high-speed energy transaction.
• Delegated Proof of Stake (DPoS) is a high-performance consensus mechanism for processing energy transaction. The public validators selected by the community will ensure the security and integrity of transactions, including execution of smart energy contracts. Eloncity’s blockchain will support over 10,000 transactions per second or 1.8 million concurrent energy exchanges at the three-minutes interval.
• A versatile and optimized smart contract platform to support energy-exchange contracts amongst community members, compute real-time equilibrium energy prices for a given location on an Eloncity microgrid and conduct agreed energy exchange.
• A “mining” mechanism to award ECT tokens to customers who use ECTP-compliant BESS for storing newly harvested renewable energy. The mining functions are written as long-running smart business contracts compatible with the CyberMiles virtual machine.
• Universal Open Chain Access Protocol layer to support applications based on any blockchain platforms such as Bitcoin or Ethereum. This universal application interface layer will facilitate ecorich applications for Eloncity. The smart contracts based on energy exchange price equilibrium will be developed per ECTP specification and be built into the hardware components of Eloncity microgrid to enable automated energy exchange. The first hardware devices to support the ECTP is the POMCube NetZero, it is a behind-the-meter (BTM) BESS. NetZero provides a buffer for storing excess renewable electricity produced on the customer premise. NetZero can make autonomous energy exchange decisions based on its built-in AI algorithm to analyze the customer energy demand profile. The demand parameters are machine-learned by “observing” the owner’s home energy use over time, similar to how the Nest thermostat functions. With the ECTP enabled devices, such as the POMCube NetZero, deployed in sufficient number on customer premises in an Eloncity microgrid, the Eloncity microgrid will be able to achieve an optimal community energy supply-demand based on local renewable resources. In addition to the described blockchain-based cryptoeconomics protocol and BESS, the Eloncity Model also aims to provide an alternative power grid network so that the community members can exchange energy independently from the utility’s T&D networks. In an Eloncity microgrid, the DCbus performs as a switching device for managing local power flows and energy exchange. The Eloncity Model aims to maximize the utilization of the DCbus with a pair of copper wires connecting each customer premise within an Eloncity microgrid to the DCbus endpoints. Each endpoint follows the timing set by the Scheduler when sending/receiving energy to/from
the DCbus and hence the pair of copper wires is no longer the best effort network. The BESS associated with each endpoint serves as ingress and egress buffer of the network, which, along with the Scheduler, prevents endpoints from overflowing or under flowing the network. An important additional benefit of the DCbus is that it saves as much as 17 percent of renewable energy as it avoids back-and-forth AC and DC conversions that are prevalent in the current entralized AC grids. The DCbus is designed to run at 1,500V to take advantage of the THE ELONCITY MODEL 35 standard technologies widely used in existing solar farms. The DCbus operating voltage can be reduced down to 1,200V so that the maximum-peak-point-tracking (MPPT) of local solar PV charging controller can be run stable without constantly changing its power-tracking algorithm to maintain the target 1,500V. Running the DCbus at 1,200V will lose little conversion efficiency.The Foundation envisions the strategic partnership with incumbent utilities to operate their own ECTPcompliant endpoints and participate in the energy exchange with Eloncity microgrids. However, the Foundation sees ideal Eloncity Model implementation to be new ZNE community constructions14. The new construction would integrate rooftop PV, BESS, and DC system during the construction phase, which eliminates 3rd party retrofit installer, higher financial cost and redundant roof insurance typically required in building retrofits. The more streamlined PV, ESS and DC system installation process in new ZNE community construction will offer significantly more cost-competitive energy from decentralized community-based renewable energy. In summary, the Eloncity Model can be easily deployed in areas that lack the electricity grid infrastructure. In the existing built environment that already have centralized AC grids, the Foundation will collaborate closely with the local utility and local government, regional ISO and appropriate regional energy regulating agencies. The Eloncity Model holds tremendous potentials to assist the utilities to fortify the existing power grids across the globe.
HIERARCHICAL CHAIN AND POWER FLOW MANAGEMENT
The Eloncity hierarchical blockchain network is a decentralized processing network. This blockchain network uses a unified utility token so that the energy valuation can be determined consistently across the entire microgrid, and the tokens will be used among the Eloncity microgrids for inter-microgrid energy exchange. Additionally, we also recognize EVs will be roaming from microgrid to microgrid, and hence the ECT can be used as a token to access EV charging when it travels outside its home microgrid. We adopt a scheme called Aggregated Routes from OSPF Protocol v2, (IETF STD 54/RFC237812) to propagate inter-microgrid energy exchange. The OSPF protocol divides the entire network into areas, and the information topology will not be redistributed to other areas. Area border routers act as summary routes, and advertise the address blocks. Eloncity Model leverages the OSPF concept to scale inter-microgrid transactions. We may adopt other protocol later, such as BGP, to improve system scalability and interoperability. While blockchain technology is still considered to be its infancy stage, the transaction processing capability will increase dramatically as we rapidly advance the technologies of the ECTP-enabled platform. By leverage the Foundation’s experiences in warehouse-scale
computing, a.k.a. Cloud computing, in which partitioning complex the power grid to easily scale the system erformance exponentially. Similarly, Eloncity Model leverage the Shard concept to scale the decentralized energy grid incrementally to increase performance as needed while mitigating large-scale grid upgrades that may leave excess capacity idles
nnecessarily. Shard is a proven technique for scaling the database to support additional geographic locations. When an Eloncity microgrid needs to import energy from a neighboring microgrid, one or more BLSPs from each microgrid will form decentralized ledger and settle the transaction amongst themselves. Note that each Eloncity microgrid may have more than one BLSP, and each BLSP may operate independently with its own decentralized energy resources that connect to multiple microgrids or act as the service point(s) for the utilities. For intra-microgrid energy exchange, BLSPs not only compete with one another but also compete equally with every other endpoint within a microgrid. For inter-microgrid energy exchange, the inter-microgrid transactions reconciliation would be settled amongst the BLSPs along the energy exchange routing paths. As future blockchain technologies improve, we may find more efficient and less hierarchical process for settling inter-microgrid transactions.
