R package: demand

This package creates diverse plots per day, weekday, month and year for peak demand power consumption of several meters to support a project, demand_acep, which was developed to make raw data of electricity consumption of 4 meters in Poker Flat Research Range (PRFR) ready to use for the further analyses. These plots lead to benefit-cost analyses and cost saving plots based on electricity rate structure from GVEA in Alaska.

Poker Flat Research Range (PFRR) is located about 40 miles North of Fairbanks, AK and serves as a sounding rocket launch facility and for other geophysical research activities. PFRR is operated by the University of Alaska Fairbanks (UAF) under contract with NASA.

Rate schedule

Service Type	Customer Charge [$/month]	Utility Charge [$/kWh]	Fuel & Purchased Power Charge [$/kWh]	Demand Charge [$/kW]
Residential	17.5	0.11631	0.09207	0.00
GS-1	20.0	0.11528	0.09207	0.00
GS-2(S)	30.0	0.06256	0.09207	14.29
GS-2(P)	30.0	0.06256	0.09207	14.29
GS-3	295.0	0.02940	0.09207	22.86

In addition, this package forecasts peak power demand using ARIMA on a daily and monthly basis. Correlation and a simple regression are also included.

To use ths package, follow the steps:

1. Install devtools

install.packages("devtools")

2. Load the package

library(devtools)

3. Install this package demand

install_github("reconjohn/demand")

3. Load the package

library(demand)

Now you are all set!

Brief description of demand charge using R package, demand

Using R package demand, peak demand, correlation, forecast, and demand charge were plotted. Refer to the followings for more details about demonstration of code from demand package and its results.

• Peak demand plot for the 4 meters here and code

• Peak demand correlation and forecasts here and code

• Demand charge reduction by implementing a virtual meter here and code

Examples are as follows:

Peak demand (kW) plot of day per month

ARIMA forecast for predicting 10 days

ARIMA forecast for predicting 3 months

Peak demand comparison between a virtual meter and the 4 meters

Cost comparison and saving

Monthly saving distribution
