Distributed Energy Resources: Economically competitive smaller, distributed power systems and storage are being installed in increasing numbers. Energy Efficiency: Consumption of energy is being reshaped by technologies that drive efficiency and change demand patterns. Decarbonization: Low-carbon technologies such as wind and solar are exceeding growth expectations. Digitization: Asset, facility and fleet level, internet- enabled applications are proliferating.

  • Distributed power technologies have created the

need for two-way power flows.

  • New technologies such as batteries are

providing opportunities throughout the transmission and distribution network.

  • It is imperative that PPL begins testing the

management of DER systems

Keystone Solar Future Project

An innovative pilot that will allow PPL system operators to have remote monitoring and management capabilities of the DER systems:

  • Interconnection Web Portal: Renewable Energy

Connection

  • DERMS: Central platform with Distributed Energy

Resource-aware algorithms for management and

  • ptimization.
  • Proof of Scalability: Customer enrollment, DERMS

pilot, technology demonstration, Drexel simulation.
