1 answer:

8 0

A microgrid's (MG) safe and reliable functioning depends on an energy storage technology, which also holds promise for the development of future power grids. To MGs, the efficient and secure operation of the storage system is extremely important.

Power management is necessary for the PV-HESS system to ensure energy supply and maximize energy savings. Energy optimization is produced by scheduling energy and controlling energy flow in the system. Peak shaving management lowers a system's peak load output, which improves power quality and energy efficiency. an enhanced lithium battery charging/discharging approach taking into account depreciation costs in day-ahead microgrid scheduling.

Joe's income is $300. He can buy 2 goods – Food and Shelter. a. (5 points) Write the budget constraint and draw the budget line

GaryK [48]

The budget constrain is how much of each good can Joe's buy and it's given by:

Income = P_f * Q_f +P_s * Q_s

P_f = Price_of_Food

Q_f = Quantity_of_Food

P_s = Price_of_Shelter

Q_s = Quantity_of_Shelter

In case a):

300 = 5*Q_f(a) + 100*Q_s

in case b):

300 = 10*Q_f(b) + 100*Q_s

To draw each line, you can make a graphic in which the x axis is Q_s and y axis is Q_f

set Q_f = 0 and solve for Q_s which gives => Q_s = 3 so, in the x axis the line will start in Q_s = 3

the same, and solve for Q_f and it'll give =>

Q_f(a) = 60

Q_f(b) = 30

So, from the start in x axis in Q_s = 3 you draw the line (a) to the y axis Q_f(a) = 60 and you draw the line (b) to the y axis Q_f(b) = 30

To get the oportunity cost you have to divide the cost of what is given up (food) by what is gained (shelter).

Oportunity_Cost_Food(a) = 5/100 = 0.05

Oportunity_Cost_Food(b) = 10/100 = 0.10

As you can see, the oportunity cost of food increase

In the current year, Borden Corporation had sales of $2,190,000 and cost of goods sold of $1,295,000. Borden expects returns in

NNADVOKAT [17]

Answer:

The entries are as follows

To record estimated returns on Sales

Debit: Sales Refund Payable Account $131,400

Credit: Accounts Receivables $131,400

To record estimated Cost of Sales returns

Debit: Inventory Returns Estimated Account $77,700

Credit: Inventory on Sales on Returns $77,700

Explanation:

To derive the figure for Sales Refund payable for the year

6% of $2,190,000

= $\frac{6}{100} * 2,190,000$ = $131,400

To derive the figure for Inventory cost on Sales Refund payable for the year

6% of $1,295,000

= $\frac{6}{100} * 1,295,000$ = $77,700
