Community Solar+: A Better Value Proposition
Community solar has helped to make solar energy an option for many people who can’t put it on their own roof. Learn how CS+ is innovating to help more innovations reach a broader audience.
Community Solar Procurement Guidance
The Community Solar Procurement Guidance Help Cities understand what roles they can play in procuring community solar, depending on their regulatory environment, and what steps they can take to do so.
Breakthrough Batteries Report
Rapid advancements in battery technology are poised to accelerate the pace of the global energy transition and play a major role in addressing the climate crisis. With more than $1.4 billion invested in battery technologies in the first half of 2019 alone, massive investments in battery manufacturing and steady advances in technology have set in motion a seismic shift in how we will organize energy systems as early as 2030.

Probabilistic Modeling of Electricity Grids
“As utilities shift toward integrating increasing amounts of DERs into their systems, they will be relying upon these resources to complement energy procurements from the wholesale market. The nature of these DERs and associated properties with respect to intermittency and various levels of reliability, however, need to be integrated into the planning process. Therefore, the Guidance Proposal recommends that the utilities identify a process to move from deterministic to a probabilistic modeling approach for distribution system planning.”[1]

Why Model Grid Infrastructure Probabilistically?
Given the small spatial scale of DER, the temporal variability, and incorporation of human preferences, optimization modeling of DERs is problematic. To cope with the number of variables and new types of uncertainty that are presented by a distributed future, it has been well documented that a probabilistic approach to modeling more distributed energy futures is desirable. An agent based model (ABM) of a probabilistic grid, one that is realistic but not real, can help integrate feedback between DER adoption and use futures with physical investments in the grid.
How?
Procedural and Pattern oriented modeling (POM) can help improve to move beyond fixed asset or market optimization towards probabilistic infrastructure investments. Cities are characterized by self-similarity, or fractal scaling. This means that a subsection of a city will demonstrate the same overall properties as larger sections and other sections. The use of the self-similar properties of cities can help, by enabling methods to “grow” realistic , but not real, energy grids based on GIS inputs.

The Scale of Smart
In a smart city there may be many different levels of decision making and data aggregation. Decision making at one level can affect decisions at another level.
