Propose a power distribution system for the newly developed locality as shown in figure 1. The locality consists of a following category of consumers:
a. Residential area: Each street of residential area consist of twelve houses there are seven streets in total
b. Commercial area consisting of a six multistory buildings
c. Hospital consisting of three blocks (A, B, C) and an Electric vehicle charging station that can charge 7 Vehicles concurrently (charging points)
The load profile of different types of customers is as follows:

s1,s2,s3,s4,s5,s6,s7, are streets and H are houses.

subject power distribution and utilization

Type of consumers Average Connected load Demand factor Diversity of groups Residential: Each house hold 0.7 KW 0.8 1.2 within a street of residential area Each EV charging point 2 KW 1 Type of consumers Maximum demand Diversity of groups/among each block Each block of hospital (A, B, C) 20KW 1.3 Each multistory building within a 5.5 KW 1.1 commercial area Let the available conductor has p = 1.78 x 10 0m. the allowed limit of voltage variations at the consumer's terminals is + 6% of rated value. It is also required to select feeder voltage as 3.3 KV and a line to line voltage of a distributor to be 400V, and feeder and distributor must pass along roads /streets. You may assume equal current distribution in each residential house. Compute diameter and length of ac distributor (feeder and a secondary distribution). In your solution you must also include the number and location of substations, topology of distributor (radial, ring etc) and give justification of your work and show all calculations. Show feeder and distribution lines running through roads / streets where possible.
