The approach of developing two group models of DER energy participation in the market is unique. We are proposing a two-part DER energy market model-a utility need business model and an independent energy aggregator-business model. We also expanded on our phase I work to enhance communication security and to develop the market model of having DERs, both customer and utility owned, participate in the energy market. In Phase II, additional DER units were added. The team has demonstrated monitoring and control of multiple DERs as outlined in phase I report including procedures to perform these operations in a secure and safe manner. With the use of a data historian technology to facilitate the aggregation, the developed algorithms and procedures can be verified, audited, and modified. The selection of standards-based communication technologies offers the ability of the system to be deployed and integrated with other utilities’ resources. The team partnered with the Midwest Independent System Operator (MISO), the local ISO, to address the energy market and demonstrate the economic dispatch of DERs in response to market signals. The primary objective of Phase II was to develop the procedures for marketing the power of the Phase I aggregated DERs in the energy market, increase the number of DER units, and implement the marketing procedures (interface with ISOs) for the DER generated power. Using the web as the communication medium for control and monitoring of the DERs, the integration of information and security was more » accomplished through the use of industry standard protocols such as secure SSL,VPN and ICCP. Procedures were created which protect the distribution network and personnel that may be working on the network. The Phase I work (DE-FC36-03CH11161) created an integrated, but distributed, system and procedures to monitor and control multiple DERs from numerous manufacturers connected to the electric distribution system. This report covers work performed in Phase II of a two phase project whose objective was to demonstrate the aggregation of multiple Distributed Energy Resources (DERs) and to offer them into the energy market. This work was performed in anticipation of being selected for Phase II of the Advanced Communication and Control of Distributed Energy Resources project. This report documents Phase I result for the Detroit Edison (Utility) led team, which also includes: DTE Energy Technology (DER provider & Aggregator), Electrical Distribution Design (Virginia Tech company supporting DEW) Systems Integration Specialists Company (real-time protocol integrator) and OSIsoft (software system for managing real-time information). The DER technologies included are a photovoltaic system, energy storage, fuel cells and natural gas/diesel internal combustion engine generators. Multi-vendor DER technologies’ representing approximately 4 MW of capacity was monitored and controlled using a web-based communication path. The real-time monitoring of the DECo system will reflect the DER control. Once it is safe to control the DER, DTE Energy Technologies will issue the control signal. This information will be exchanged from Detroit Edison to DTE Energy Technologies. Prior to issuing control of a DER, the safety of the distribution network and personnel needs to be more » taken into account. For the calculated suggestions to be used by the Detroit Edison operators, procedures were developed to allow an operator to operate a DER by requesting operation of the DER through DTE Energy Technologies. The availability information will be exchanged from DTE Energy Technologies to Detroit Edison. Part of the suggestion algorithm takes into account the operational availability of DER’s, which is known by the Energy Aggregator, DTE Energy Technologies. The Distribution Engineering Workstation (DEW) (a power flow and short circuit modeling tool) was modified to calculate the real-time characteristics of the distribution network based on the real-time electric distribution network information and provide DER operating suggestions to the Detroit Edison system operators so that regional electric stability is maintained. The project objective was to create the communication and control system, the process and the economic procedures that will allow owners (e.g., residential, commercial, industrial, manufacturing, etc.) of Distributed Energy Resources (DER) connected in parallel to the electric distribution to have their resources operated in a manner that protects the electric utility distribution network and personnel that may be working on the network.
