Advanced Algorythym To Analyze 15 Minute Smart Meter Data to Optimize PV and Battery Sizing and Usage

This is kind of an advanced project, as it will be customized for Hawaii weather and rate payers, based upon their existing PV, their desire for more power in the future.   More power in the future may be an anticipated EV, or desire to run the Aircon more (or add Aircon).

It will require access to the customer's HECO 15 minute data, which assumes and requires that you have a smart meter.    We are not recommending that you go out of your way to get a Smart Meter, if you don't already have one, there are upsides to the data, but potential EMF downsides too.  

The spreadsheet that it came up with has logical sheets and columns, but no formulas, I'll work on this more as time allows.

Creating a spreadsheet to parse and analyze HECO smart meter data in 15-minute increments, dividing the load profiles into day and night for both summer and winter, is indeed a detailed task. However, I can create a template to help you get started with this analysis.

The spreadsheet will have the following components:

1. Raw Data Input: A place to input the HECO smart meter data.
2. Time Parsing: Parsing the data into 15-minute increments and categorizing into day and night.
3. Seasonal Parsing: Separating the data into summer and winter profiles.
4. Load Profiles: Calculating the load profiles for day and night in both seasons.
5. Battery and PV Sizing: Sheets to calculate the required battery size and potential PV array size increase based on the load profiles.

Here's how the spreadsheet will be structured:

Sheet 1: Raw Data Input

• Columns for Date, Time, and Energy Consumption (kWh)
• Example Columns: Date, Time, Energy (kWh)

Sheet 2: Parsed Data

• Additional columns to categorize the data into day/night and summer/winter
• Example Columns: Date, Time, Energy (kWh), Day/Night, Season

Sheet 3: Load Profiles

• Summarize the parsed data to show average day and night consumption for summer and winter
• Example Columns: Day/Night, Season, Average Energy Consumption (kWh)

Sheet 4: Battery Sizing

• Calculate the required battery size based on the load profiles
• Example Columns: Day/Night, Season, Required Battery Size (kWh)

Sheet 5: PV Sizing

• Calculate the potential PV array size increase based on the load profiles and seasonal solar production
• Example Columns: Season, Current PV Size (kW), Required PV Size Increase (kW)

Let's create a basic structure in a spreadsheet format:

Sheet 1: Raw Data Input

Date	Time	Energy (kWh)
2024-01-01	00:00	0.25
2024-01-01	00:15	0.30
...	...	...

Sheet 2: Parsed Data

Date	Time	Energy (kWh)	Day/Night	Season
2024-01-01	00:00	0.25	Night	Winter
2024-01-01	00:15	0.30	Night	Winter
...	...	...	...	...

Sheet 3: Load Profiles

Day/Night	Season	Average Energy Consumption (kWh)
Day	Summer	15
Night	Summer	10
Day	Winter	12
Night	Winter	8

Sheet 4: Battery Sizing

Day/Night	Season	Required Battery Size (kWh)
Day	Summer	20
Night	Summer	12
Day	Winter	18
Night	Winter	10

Sheet 5: PV Sizing

Season	Current PV Size (kW)	Required PV Size Increase (kW)
Summer	5	2
Winter	5	3

Step-by-Step Instructions

1. Raw Data Input: Input your HECO smart meter data into Sheet 1.

2. Parsed Data: Use formulas to categorize the data into day/night and summer/winter.

   • Day: 06:00 to 18:00
   • Night: 18:00 to 06:00
   • Summer: Define months as per local climate (e.g., May to October)
   • Winter: Define months as per local climate (e.g., November to April)

3. Load Profiles: Use AVERAGEIF or similar functions to calculate average consumption.

4. Battery Sizing: Calculate based on peak loads and desired backup duration.

5. PV Sizing: Adjust based on seasonal solar production data and load profiles.

I will create an example Excel spreadsheet based on this structure and share it with you. Let's begin by constructing this template.

Creating the Spreadsheet

Here is the structure and some formulas to help you set up the spreadsheet:

Parsed Data Example Formulas

• Day/Night Column:

  excel
  
  

=IF(AND(HOUR(B2)>=6, HOUR(B2)<18), "Day", "Night")

Season Column:

excel

• =IF(OR(MONTH(A2)>=5, MONTH(A2)<=10), "Summer", "Winter")
  

Load Profiles Example Formulas

• Average Energy Consumption (Day/Summer):

  excel
  

• =AVERAGEIFS(C:C, D:D, "Day", E:E, "Summer")
  

I will create an Excel spreadsheet based on these guidelines and provide you with a downloadable link shortly.
