IEEE Smart Grid member Ângela Paula Ferreira explains how smart microgrids use conservation voltage regulation (CVR) to reduce energy consumption. From the point of view of utilities, CVR implementation presents the opportunity for peak shaving and grid loss reduction, taking into consideration both transformers and distribution lines. On the other end, due to the reduced energy consumption, it may represent a loss of revenue, as occurs with many demand response programs. To read this article in full, click here.

The technological components of a “smart city,” including everything from smart grids and driverless cars to automated buildings and advanced sensors, can be complicated. But the core question behind the purpose of a smart city is quite simple: does it make human lives better? That’s the key theme explored in the webcast “The Connected City: Trends and Developments Driving Smart City Innovation,” produced by MIT Technology Review and IEEE Collabratec. Three influential subject matter experts with different backgrounds in developing smart cities delve into how these cities influence their human populations.

The stochastic nature of loads has been a major concern and a persistent challenge both for power system operators and the involved regulating authorities. However, the ever increasing penetration of renewable energy sources (RES) during the recent years has introduced additional factors of stochastic behavior, which affect severely the economics, the technical limits and the operating capability of the power system. Assuming on operator initiatives and/or stricter regulating frameworks implies that the deregulated energy market model will be inconsistent (conventional generators catering for stochastic sources) or that there will be (eventually) a roof to RES penetration.

The increasing adoption of variable DERs challenges the traditional planning and operation practices of utility distribution systems. These systems have been traditionally radial and had single directional power flows and protection schemes, whereas with DERs, the power flows will become bi-directional and impact the circuit protection and control schemes. Like other utilities, ComEd is examining the potential of a DSO pilot implementation to investigate the relationship between DER deployments and DSO, as well as the potential DSO applications that can facilitate DER integration and benefit both end-use customers and the system. Similar to transmission system operators, the DSO would act as an independent aggregator by interfacing distributed generators and network owners and by managing a distributed generation market.

Note to our Members:

Beginning October 1st, all IEEE Smart Grid content including videos, past webinars, interviews and archived newsletter articles will be removed from the Resources Page of the website. Members may locate this content on the newly developed IEEE Smart Grid Resource Center. In the future, you may visit the Resource Center, by clicking on the "Resource Center" icon above near our social media icons.

Anyone may browse the Resource Center, but access to the content will depend on one's IEEE membership status. In order to retrieve the content, members will be directed to "Sign In" in the top right hand corner of the page. You may use your IEEE credentials to sign in. If you are not an IEEE member, you may create an account. Once you have logged in, you will notice a three-tier pricing schedule to access the content:

  • If you are a member of one of the 14 partner organizational units of IEEE Smart Grid, the content on the IEEE Smart Grid Resource Center will be free to you.
  • If you are not a member of one of the 14 partner organizational units of IEEE Smart Grid, but you are an IEEE member, the content on the IEEE Smart Grid Resource Center will be at a discounted charge to you.
  • If you are not a member of one of the 14 partner organizational units and not a member of IEEE, you will be asked to pay a fee to access any of the content on the IEEE Smart Grid Resource Center OR you may create an account to browse the Resource Center and become a member of any of the 14 partner organizational units in order to retrieve the content at no cost to you.
  • Thank you for your continued interest in IEEE Smart Grid!
