Technology advancements in renewable generation, power electronic devices, and advanced computing expedite a decarbonized, decentralized, and digitalized grid. These advancements also enable a role transition for traditional utility customers, enabling the role of “prosumers” who provide power to the grid with distributed energy resources (DERs) that exceed their demand and who adjust the timing of their energy consumption to energy pricing. Although this role change can alleviate stresses on the grid and support a clean generation future, it sparks multiple challenges for the power industry, spanning system operation to future grid planning. One class of problems relates to visibility. Utility operators usually do not have oversight over rooftop solar photovoltaics (PVs) or site batteries. These behind-the-meter (BTM) DERs tend to cluster in neighborhoods, which can cause or exacerbate issues with reverse power flow, power quality, and load masking. In turn, these problems increase the risk of relay miscoordination and power interruptions during normal grid operations. Aging grid infrastructure adds an additional layer of uncertainty to the operational characteristics of the nonvisible generation stack, and electrification adds a layer on top of that, with the increasing penetration of electric vehicles adding stochastic loads to the system. These challenges are not only operational, they also relate to the near- and long-term planning of the grid. Because planners cannot anticipate where and when the new DER interconnections will be requested by customers, requests may overturn the original grid upgrade plan and reshape resource distribution.

The canary island of el hierro has become a global example of good practices in sustainability policies. Also known as the Meridian Island (Figure 1), El Hierro received the declaration as a United Nations Educational, Scientific and Cultural Organization (UNESCO) Biosphere Reserve in 2000. The most western of the archipelago is today a first-rate island with palpable examples of sustainable development that can be replicated on other parts of the planet. The most obvious example is found in the operation of its hydro-wind power plant, with which it has managed to become one of the first energy-isolated territories in the world to aspire to energy self-sufficiency. Its second great challenge is the advancement of its Sustainable Mobility Plan and the continuity of the application of energy-saving policies.

Island power systems around the world are, in many ways, leading the power industry in developing strategies for accommodating high levels of variable, weather-dependent generating resources. These systems often have relatively high energy costs associated with serving their loads with traditional fossil resources. As such, they are highly motivated to simultaneously reduce their energy costs and emissions footprints with renewables. The successes of these islands can show the way forward, not only for other islands, but ultimately for large, interconnected power systems. In additional to technical advances, innovations in business arrangements can provide equally important learning for the entire industry. Here we examine one such innovation.

As levels of wind, photovoltaics (PVs), and battery energy storage on power systems rise, it is useful to be able to quickly compare how much generation (instantaneous power and annual energy) comes from these inverter-based resources (IBRs). A commonly used metric is the percentage of inverter-based generation (% IBR) in a dispatch scenario (as a percentage of the total generation or total load), which can be useful for estimating when certain operational challenges arise (high rates of change of frequency, underdamped control interactions, low system strength, low fault current availability, and so on). Another similar and commonly used metric pioneered on the relatively large island of Ireland, system nonsynchronous penetration (SNSP), is similar to the % IBR and is subject to similar limitations. SNSP has the advantage of handling high-voltage dc in a defined way.
