The goal of the project is Design a small-scale simulated model of the power distribution network and analyze the impact of allowing consumers to inject power into the grid. This is the first step to develop electricity markets at the distribution system level and incorporating prosumers as providers within the public utility system.

Problem Definition[edit]


In the modern power grid, consumers are transforming into the so-called prosumers where electric power end-users could also generate their own energy from renewable resources such rooftop photovoltaic panels (PVs) or have stored energy in batteries (electric vehicle) and inject it back into the grid to sell the excess energy. This results in reverse power flows that could have an impact on the stability and the economics of the operation of the power distribution and transmission systems. The power distribution system could benefit from this local distributed generation if the adequate controls and sensing are developed.



  • Data analytics to increase efficiency in the distribution​
  • Profitable electric power pricing for Avista and the prosumer​
  • Possible of semi-automated trading of power​


The OpenDSS is a comprehensive electrical power system simulation tool primarly for electric utility power distribution systems. It supports nearly all frequency domain (sinusoidal steady‐state) analyses commonly performed on electric utility power distribution systems. In addition, it supports many new types of analyses that are designed to meet future needs related to smart grid, grid modernization, and renewable energy research. The OpenDSS tool has been used since 1997 in support of various research and consulting projects requiring distribution system analysis. Many of the features found in the program were originally intended to support the analysis of distributed generation interconnected to utility distribution systems and that continues to be a common use. Other features support analysis of such things as energy efficiency in power delivery and harmonic current flow. The OpenDSS is designed to be indefinitely expandable so that it can be easily modified to meet future needs. [[2]]


Design Considerations[edit]

We propose to design, develop, test, and evaluate a software application that would enable prosumers and consumers to trade power on-demand or semi-automatically between themselves, with utility oversight, or with the utility. Such system would enable prosumer-consumer power trading with some of the characteristics of sharing economies and markets. Furthermore, the goal is that such system would lead, in the long run, to semi-automated trading of power similarly to current financial high-speed trading systems between smart-grid-enabled consumers, prosumers, and the utility. We will evaluate and select the best software technologies and design and develop a prototype software system that enables these transactions through an online web and/or app interface. Such system will enable Avista to create a new market for prosumer-consumer power trading and to plan, manage, and control such market and the flow of power through its network.


Product Requirements[edit]

We are using OpenDSS to handle the modeling aspect of this project. The reason is, it's open source so we don't have to deal with licensing.​The OpenDss Model needs to be changed dynamically.​Since we are dealing with renewable energy, we will have to consider how to implement PV panels, EV's, and wind in our model.​


Specific Project Plan The proposed tasks for the software effort are:

  • T1: Meet with Avista® representatives to gather system requirements and understand information interchange interfaces such as to the Advanced Metering Infrastructure.
  • T2: Design and model the system using modern system modeling tools such as ERD.
  • T3: Develop the database architecture and schema and select a DBMS.T4: Analyze security risks and design and implement security mechanisms.
  • T5: Develop a simulated model of the power distribution network.
  • T6: Design and sketch Web and/or App interfaces: User and Administration.
  • T7: Build the prototype software using a fourth-generation application development tool.
  • T8: Integrate the transaction control system prototype with the distribution model.
  • T9: Design and perform tests for: Functionality, Usability, and Security.
  • T10: Produce user and administrator usage guides.

Final Design[edit]

We want this model to be changed dynamically with adding varying loads and generators​ We also want it to be able to communicate with the interface that is being created.​


Requirement Test Test subject Target Date Result recommendation
The use of OpenDSS Use the OpenDSS to support the design and operation of power distribution system The power distribution system simulator 10/22/2018 We have just download the OpenDSS and begin to learn how to use it Need more instructions about the OpenDSS
Doing more research by ourselves Finishing the research including the requirements about software and other factors The power distribution system simulator 11/1/2018 We have done a lot of researches on our own and I think it has enough time for us by the due time Wikipedia is very useful for us
