With the rise in Electric Vehicles’ availability in Midwest states, it’s time to acknowledge the alternatives for charging EVs at MISO, the regional grid operator. Aggregated EVs is usually a distributed power useful resource (DER). Therefore, aggregators are ideally positioned to bid EVs into the MISO market. MISO and different grid operators can allow EV prospects by permitting aggregated EVs to take part within the power markets.
This weblog is a component three of three collection of postings to resolve why EV prospects look brighter within the Midwest, even when any of the Midwest states shouldn’t be California. See half 1 right here. And half 2 right here.
Storage goes right into a legacy platform, not a brand new market platform
It isn’t any secret that MISO is constructing the next-generation market techniques platform in parallel with its present market platform. FERC has rejected MISO’s request to increase the Electric Storage Resource (ESR) market participation mannequin within the new platform. So, MISO is getting ready to combine ESRs on legacy market techniques by June 2022.
MISO markets have loads of expertise with aggregators, principally from Illinois, from a requirement response product perspective. Demand response reduces demand, which is without doubt one of the working modes of an aggregated EV resembling Electric School Buses. As the Advanced Energy Economy (AEE) lately launched report on Order 2222 suggests, 480,000 faculty buses serve greater than 25 million college students within the US. Hence, we will anticipate MISO to see market integration of aggregated electrical faculty buses.
It is vital to recollect the FERC Order 841 definition of ESR at this stage, which states:
“A useful resource able to receiving electrical power from the grid and storing it for later injection of electrical power again to the grid.” FERC additionally mentioned, “ESRs situated on the interstate transmission system, on a distribution system, or behind the meter fall underneath this definition.” Hence it’s clear that aggregated EVs can function as demand response and ESR at MISO.
MISO lagging in Distributed Energy Resource (DER) penetration in real-time markets
FERC’s broad definition of DER in Order 2222 means many alternatives for distributed assets at MISO. A DER is outlined by FERC as “any useful resource situated on the distribution system, any subsystem thereof or behind a buyer meter.”
A latest “State of the Market” report from MISO’s market monitor suggests MISO has 13,675 MW of various sorts of planning demand response. Planning DR means packages that take part in the direction of assembly the MISO planning reserve margin. The majority of those DR packages are “Load Modifying Resources (LMRs).” MISO has totally different sorts of LMRs: behind-the-meter technology LMRs, demand response LMRs, emergency DR LMRs, and power effectivity LMRs. These a number of market merchandise for planning DR imply aggregated electrical faculty buses have a number of methods to register with the MISO market registration course of.
Even although MISO has a considerable amount of planning DR, MISO has a restricted quantity of operations DR. These assets, known as Demand Response Resource (DRR) Type I and II, are lower than 1,000 MW out of 13,675 MW. Operations DR means DR packages that may react to MISO operator indicators in real-time. As the AEE report asserts, DERs resembling aggregated faculty buses ought to have the power to replace their real-time provides in organized markets.
FERC Orders 841 on power storage and 2222 on DER Aggregation push MISO to interconnect aggregated applied sciences
While MISO is 12 months away from implementing Order 841 ESR available in the market platform, it’s 9 months away from submitting a compliance plan for Order 2222 on aggregated DER. This timeline means MISO is working with its stakeholders to suggest a plan, take stakeholder feedback and in the end file at FERC in April 2022. We don’t know the implementation date for Order 2222 at MISO.
Order 2222 states aggregated EVs, fleets of electrical vans, and electrical faculty buses should first interconnect with electrical distribution corporations. Once the distribution firm research them for distribution grid impacts, aggregated EVs should…
