Electric Vehicle Roaming Scenarios
Area of Application
 Consumer premise,Distribution
Description
 The customer plugs the PEV into the grid at a location different from their "home" location. Different scenarios address who and how the PEV charging will be accounted for and billed. These roaming scenarios include: The customer connects their PEV to the energy portal at another premise. The premise customer pays for the energy use. This scenario could include bundling the electrical charging with other services provided by the premise (e.g. hotel or mobile home facility), or could include private payments between the parties (payment with cash or a credit card, such as is currently done at gasoline stations). The PEV customer just pays what is due, without reference to any PEV program they are enrolled in. • The customer connects their PEV to the energy portal at another premise. The PEV customer pays for the energy use directly with the utility, such as with a credit or debit card. In this scenario, the customer would get billed at the rates in their PEV tariff. • The customer connects their PEV to the energy portal at another premise outside the enrolled utility`s service territory. In addition to the previous 2 scenarios, the customer could become a "guest" of the external utility and pay rates as such a guest, or could indicate the PEV program they are enrolled in at their "home" utility, and pay those rates. The external and "home" utilities would then make a settlement between them on any differences. • The customer with a PEV that is not enrolled in any program (or cannot prove enrollment) connects their PEV to the energy portal at another premise. Either private party arrangements would be needed (first scenario) or "guest" arrangements (third scenario) would be used for payment. • The customer connects their PEV to the energy portal at a public location, multi-family dwelling, or workplace infrastructure. Either private party arrangements (first scenario) or direct utility interactions (second scenario), or "guest" arrangements (third scenario) would be used for payment.
Scope
 Customers are interested in fueling vehicles with electricity. Electric Vehicles (EV) and Plug-in Electric Vehicles (PEV) are emergi transportation options for customers. Electric utilities desire to support these emerging loads with electricity at "off peak" times wh energy costs are low and generation and power delivery assets are underutilized. PEV manufacturers are interested in working w utilities to develop customer rates/programs which could provide customers with an increased incentive to purchase a PEV. Utilities may offer the Customer a PEV tariff that provides a low rate for off-peak charging and a higher rate for on-peak charging.

IC-2 ISO publishes indicators of grid conditions with expectations consumers will adjust usage
Area of Application
 Consumer premise,Distribution,Operations
Description
 Demand response has been an active part of the energy environment for years. The recent Energy Policy Act of 2005 and efforts to leverage the technologies available with the smart grid have provided new momentum for growing both dispatchable and price responsive (non-ISO dispatchable) demand response. It is expected the electricity market efficiency improves and investments in transmission and generation can be displaced with a larger percentage of demand response. The concept of price responsive demand response is that as wholesale prices vary, and as long as they are highly correlated with retail prices, consumers can choose to save money by decreasing consumption when prices rise, or to increase revenue by increasing production when prices fall, where technically and economically feasible. This paradigm relies on an important assumption that wholesale prices, which reflect system conditions, are strongly correlated with retail prices and provide consumers with appropriate cost incentives to respond in ways that enhance system reliability and efficiency.
Scope
 The goal of this use case is to communicate system conditions through a grid condition indicator generated from the ISO`s published Locational Marginal Prices (LMPs) as well as other grid condition information to trigger demand response activity.` These demand response actions are taken outside the ISO market; however, it is anticipated that such load adjustments will contribute to the needs of the system if implemented appropriately. The ISO does not define in this use case any specific attributes of demand response programs or products (i.e.: response time, duration, etc.).

The customer`s Customer Building Automation System receives the RTP signals from the Energy Service Provider and performs optimizations on the best mix of load reductions and DER Device function based on the customer`s criteria. At the beginning of each interval, the Customer Building Automation System sends the appropriate commands to the DER Device Manager to initiate the DER Device functions for that interval. The DER Device Manger processes those commands, initiates the DER Device utilization and monitors the DER Device(s) for compliance with commands. Any failure to produce the scheduled DER Device results in an alarm broadcasted to the Customer Building Automation System where the customer can take appropriate action. The monitored DER Device activity is made available in real-time to the Customer Building Automation System where the data can be made available to the customer and Energy Service Provider.
Scope
 The DER Device management system controls the DER Device(s) according to the DER Device schedule. The customer`s Customer Building Automation System receives the RTP signals from the Energy Service Provider and performs optimizations on the best mix of load reductions and DER Device function based on the customer`s criteria. At the beginning of each interval, the Customer Building Automation System sends the appropriate commands to the DER Device Manager to initiate the DER Device functions for that interval. The DER Device Manger processes those commands, initiates the DER Device utilization and monitors the DER Device(s) for compliance with commands. Any failure to produce the scheduled DER Device results in an alarm broadcasted to the Customer Building Automation System where the customer can take appropriate action. The monitored DER Device activity is made available in real-time to the Customer Building Automation System where the data can be made available to the customer and Energy Service Provider.

Software Demonstration of Intentional Islanding
Area of Application
 Consumer premise,DER
Description
 Islanding refers to the isolation of the compact network. This is done by opening the network protectors upon recognition of a system fault (or the network operator decides to isolate the switch) Once this happens, the compact network must dispatch the local generation equipment and, should the local generation not be sufficient to meet the normal loads of the grid, demand reduction occurs through the customer load controllers. Alternatively, if localized energy storage is available, the storage can provide ride-through capability during the islanding event depending on the economics and timing requirements to re-establish compact network power flows. Figure 1 below shows a physical depiction of a generic situation with loads, network protectors, and agents. Storage devices could be situated within any portion of the network either on the customer- or utility-side of the meter in order to balance power flows and provide for temporary ride-through on the network from grid contingencies.
Scope
 The use cases in this project concentrated on a small subsection of a major city`s power grid called a compact network or Microgrid. A schematic of a typical compact network is shown in Figure 2 and services 18 to 25 managed customers within an approximate 12 square block area. It is estimated that each Microgrid will serve 10 to 15 megawatts of load. In this figure the boxes labeled NP are network protectors that can be used to shut off load through the associated transformer. The boxes labeled LC are load controllers used to shed load with the associated meter M. Generators G can be used to provide power to and effect VAR management within the compact network. The sensors denoted by the circles labeled S represent arrays both monitoring and control devices and have the functions as stated on the schematic labels.

Island Mode
Area of Application
 Consumer premise,Distribution,DER,Operations
Description
 A local energy community - With the new Clean Energy Package, private households are encouraged not only to generate and consume energy, to market the flexibility of controllable producers and consumers in the future, but also to make energy available to each other and to share generated energy. In the future energy distribution network, the new regulatory framework, technical developments and grid fee mechanisms canmotivate households to found and/or join energy communities with the aim to maximize the consumption of locally generated energy. Communities with a high penetration of photovoltaic systems and correspondingly large installed generation capacity can be expected to generate an energy surplus during times of peak generation and low local demand, and vice versa to run into an energy deficit during seasons of low generation. Surplus energy can be stored and shifted to times of low generation in order to satisfy temporary demand and hence increase the degree of self-sufficiency up to 100%. Networks: LV Markets: None
Scope
 Implementing of an Energy Management System that operates a specific low voltage network in virtual island mode, i.e. minimizing the power exchange with the connected medium voltage feeder by utilizing available flexibility (local energy storage systems and controllable loads)

Energy Delivery
Area of Application
 Consumer premise,Distribution,DER,Operations
Description
 Energy communities with a high proportion of self-generation and flexible consumers and storage can maximize the self-consumption of locally generated energy. These communities are unlikely to meet their own needs with locally generated energy throughout the year and will potentially run into energy-deficit in times of low local generation. Energy deficits could be compensated by the supplying distribution network. To reduce the stress on the mid-voltage feeder and reduce overall network cost, energy deficits occurring could be forecasted and delivered in discrete packages ahead of time at fixed time slots and be stored in local storages until demand arises. Networks: LV, MV Markets: None
Scope
 Electricity is delivered to local energy community during predefined timeslots, outside of which the community reverts to temporary island-mode.
