As power systems decarbonize their generation, they will experience a new challenge. All zero-emission electrical power systems produce significant amounts of surplus clean electricity. The current practice in most jurisdictions is to curtail the excess production that can’t be stored or exported to neighboring power grids. The webinar will present data from Ontario, Canada. Ontario’s power system is now about 94% carbon-free and needs to manage significant amounts of surplus clean electricity. About half is stored or exported at low spot market prices to neighboring power grids and about half is currently curtailed (wasted). This webinar proposes some retail electricity price reforms and smart grid functionality that can enable consumers to cost-effectively use that surplus clean electricity when it is available to displace their fossil fuel use, reduce their overall energy bills and lower their atmospheric emissions.

Residential distributed energy resources (DER) such as solar PV and batteries are becoming increasingly common. This is creating opportunities for DER owners to provide system-level services through aggregators. However, as the volume of DER providing services increase, the more necessary is to ensure the integrity of the distribution network; guaranteeing that voltages and power flows remain within limits. But the big barrier for distribution companies is that they cannot directly manage DER or aggregators. To overcome this barrier in an effective way, this webinar presents and discusses the concept of meter-level operating envelopes. In this concept, distribution companies calculate, in real-time or day-ahead, operating envelopes (time-varying export or import limits) at the connection point of the customers (where the meter is). This information is then given to aggregators for them to consider it as a hard constraint when deciding how to manage their DER portfolio. The concept and its effectiveness are illustrated using a realistic Australian distribution network. Finally, the webinar discusses the challenges associated with the calculation and implementation of such operating envelopes, including smart meter data, interactions among the three phases, fairness, and reactive power.

Storage is a generation, transmission, and distribution asset. Hence the services storage provides, and the revenue from storage should include all the services provided. FERC Order 841 treats storage as a generation asset. Stakeholders need to know all the costs and benefits of storage, so that storage is valued appropriately for consumer benefits. Utilities are focused on a single attribute of storage like congestion deferral, or capacity value. Or state storage is not cost-effective right now. Because of focusing on one single revenue stack.
Since storage is all of the above - generation, transmission, and distribution assets, it is a bit complex. But, by focusing on the primary value like a peaker replacement or reducing peak demand charge utilities and their customers realize the benefit. Rakon Energy will provide independent cost estimates from talking to various vendors and emphasize the multiple value-stack benefits from storage.

Electrical Energy Storage has played three primary roles. First, it reduces the cost of electricity costs by storing electricity during off-peak times for use at peak times. Secondly, it improves the reliability of the power supply by supporting the users during power interruptions. Thirdly, it improves power quality, frequency, and voltage. Electrical Energy storage is expected to solve many problems, including excessive power fluctuation and undependable power supply due to the use of high penetration levels of renewable energy. Electric vehicles with batteries are the most promising technology to replace fossil fuels by electricity from mostly renewable energy sources. This presentation will highlight the needs and the roles for electrical energy storage.

Massachusetts became the pioneering state to initiate policymaking for a clean peak energy standard (CPES) that seeks to incentivize technologies providing clean energy or reducing consumption during peak demand, in order to reduce ratepayer costs and avoid GHG emissions. The concept holds broader appeal given its many parallels with the RPS construct and mandates load serving entities to meet a pre-determined percentage of annual retail electricity sales by procurement of clean peak energy certificates (CPC). Energy storage holds a role of prominence in that policy objective by virtue of its versatility in shifting clean energy to times of peak demand and also providing ancillary services to the grid. Additional revenues from CPC coupled with declining capital costs therefore promise to create a better business case and consequently drive the storage industry. This webinar will cover the proposed CPES policy construct and emphasize on the economics of applications involving energy storage.

Blockchains have attracted considerable interest and are reported as a promising technology that could deliver significant benefits and innovation in the energy sector. The webinar will provide a comprehensive overview of fundamental principles that underpin blockchain technologies, such as system architectures and distributed consensus algorithms. Next, we provide an overview of blockchain solutions and business cases in the energy industry. This summarises the results of a comprehensive review of the potential of blockchain technology in the energy industry, which the presenters completed for the National Research Centre for Energy Systems Integration (CESI) in the UK.
Our review included 140 blockchain initiatives (both research projects and start-ups), which are systematically classified into different groups according to their field of activity, implementation platform and consensus strategy used. Opportunities, best practices and challenges encountered will be discussed for a number of applications, ranging from emerging peer-to-peer (P2P) energy trading and Internet of Things (IoT), to automation of decentralised marketplaces, EV charging and e-mobility. The webinar concludes with a discussion of challenges and market barriers the technology needs to overcome for mainstream adoption.

Electrical power infrastructures are changing dramatically around the globe due to Smart Grid initiatives, the establishment of renewables and the resulting distributed nature of creating electricity. As a result, the power network faces great challenges in generation, transmission and distribution to meet new and many times unpredictable demands of providing coherent electricity supply. Electrical Energy Storage (EES) has been considered a game-changer with a number of technologies that have great potential in meeting these challenges.
However, the wide variety of options and complex performance matrices can make it difficult to appraise a specific EES technology for a particular application. This presentation intends to contribute information that will give a Smart Grid user a clearer picture of the state-of-the-art electrochemical technologies available, and where they would be suited for integration into a power generation and distribution system.

Blockchain is considered to be a foundational technology that will create a new decentralized Internet layer. Most of today's Blockchain development has been focused on Bitcoin and Cryptocurrency. However, the vertical markets, particularly the Energy sector, will benefit from the adoption of Blockchain as a potential disruptive technology that complements the insertion of Internet of Things (ioT) that improves grid device-system management, cybersecurity, and also enabling a new layer of energy trading.
This webinar introduces a unique perspective of Blockchain applied to Smart Grid. It describes the basic principles of Blockchain, how it works, the key underlying technologies, the challenges and applications. It focuses on the enterprise energy segment, and the key elements and protocols.
It will introduce the Blockchain Energy Reference Framework that is being created for the IEEE standards, addressing the Blockchain application, process, data and network layers. Finally, it will present some specific Smart Grid Blockchain use cases, including IoT Energy Trading and Transactive Energy.

With the significant increase in integration of renewable energy generation into the electric grid, market-based transactive exchanges between energy producers and prosumers will become more common. Transactive energy systems (TES) employ economic and control mechanisms to dynamically balance the demand and supply across the electrical grid. Emerging transactive control mechanisms depends on a large number of distributed edge-computing and Internet of Things (IoT) devices making autonomous/semi-autonomous decisions on energy production, energy consumption and demand response. However, the electric grid cyber assets and the IoT devices are increasingly vulnerable to attack. TES will likely have similar vulnerabilities and cyber attacks specially with financial interest motives of stakeholders, which could affect the operation of the power grid. Therefore, new analytical methods are needed to continuously monitor these systems operations and detect malicious activity. In this research work, various components of transactive energy systems are modeled and simulated in detail. Various cyber attack models are developed based on identified vulnerabilities of TES. A deep learning approach called deep stacked autoencoder (SAE) and MAE based techniques are utilized to detect possible anomalies in market and physical system measurements. The proposed technique is validated for satisfactory performance to detect anomalies and trigger further investigation for root cause analysis.

The optimal mix of distributed energy resources for a project or microgrid is dependent on many factors including project load profile, available rate structures, geographic location, space considerations, and project goals. Hourly modeling of the project over the course of a year can be used to estimate the savings and return on investment for different combinations of distributed energy resources including renewable generation, CHP generation, energy storage, and demand response. Different rate structures including time of use and real time price for electricity supply should be considered. Different operating modes for dispatching local generation assets should be evaluated including dispatching based on bulk electricity price and dispatching based on minimizing demand changes. Finally, project goals must be considered. For example, one project might prioritize maximizing renewable generation and minimizing environmental impacts. Another project might prioritize achieving full islanding capability for resiliency during grid outages.
