Design Challenge

Design a Microgrid to support a Wastewater treatment plant. This would include retrofitting the following units to an existing WWTP and updating controls to allow for islanding. This Project is sponsored by Commercial Solar Works.

• Biodigester
• Synchronous Generator
• Solar Array
• Battery Storage

Objectives: Limitations:

• Reduce sludge disposal costs
• Save on energy costs
• Allow Plant to operate during a

grid outage

• Site space
• Current site loads and flow rates

must be considered

• Cost efficient materials
• 1 Day of islanded operation

Elements: Biodigester

• Role: Dispose of waste slurry and

produce methane to run generator

• Size: Based on flow rates of waste

slurry

• Responsibility of ENVE team

Elements: Generator

• Role: Burn Methane to create three

phase AC Power to run plant loads

• Size: Based on Methane production

and energy needs of the plant

• Type: Synchronous generator
• Controls: Constant power or droop

control

Elements: Solar Array

• Role: Supplement the Generator
• utput to fulfill loads of the plant

when islanded

• Size: Based on solar potential of site

and difference between Generator

• utput and loads
• Controls: Maximum Power Point

Elements: Battery Storage

• Role: Be a dispatchable source to

account for changes in solar production

• Size: Based on needs for

dispatchable energy, will be charged during peak hours to be used in off hours

• Controls: Droop Control

Deliverables

1. Site plan: location, choose a WWTP, Choose equipment locations. Document showing land parcel with three sources added in 2. Riser diagram: existing electrical infrastructure with 3 sources integrated in 3. Energy Production Model: How much methane can be produced, how much PV will be needed
