Intelligent Building Energy System

This research proposal outlines a project to design a low voltage DC microgrid for rural electrification in Sri Lanka. The objectives are to select a rural area with limited grid access, determine average electricity demand and load profiles, identify suitable distributed energy resources, and design an integrated DC microgrid with energy storage and controls. A protection system will be investigated and modeled to protect the DC microgrid under different fault conditions. The expected start date is October 5th, 2016 and the project duration is one year and three months. Key activities include collecting data, modeling the system in PSCAD software, researching DC microgrid protection methods, designing protection, and preparing a final report with conclusions and recommendations.

agent control techniques

b) Objectives:

Brief Description

With the increased concerns on environmental factors and increasing demand for electricity,
renewable energy sources have captured a spectacular place in the line of energy sources. Microgrids
enable to integrate distributed energy sources offering higher reliability. Microgrids be AC, DC or
Hybrid depending on the bus voltage concerned.
The debate AC verses DC is historical and as old as the power systems itself [1]. DC microgrids offer
plenty of advantages when compared to an AC microgrid. Most of the renewable sources like solar
PV can be integrated to a DC microgrid with reduced conversion stages. Energy storage elements
will require a single DC-DC converter when connected to a DC microgrid. Therefore, compared to
an AC microgrid the overall efficiency will be increased when using a DC microgrid. In addition to
this the key advantage of LV DC microgrid is that low risk of dangerous electric shock. Most of the
modern electronic loads, LED lighting, telecommunication equipment, electric vehicles (EV) and
HVAC systems are operated on DC power.
Most of the commercial buildings, data centers, telecommunication and broadcasting stations, space
crafts, ships, rural electrification systems and EV charging centers use DC microgrids. DC microgrid
is an emerging concept, but still standards and regulations are not documented, which is an obstacle
for the development of DC microgrid technologies.
Moreover DC microgrids are used for rural electrification. For example in north India authorities
have used 24 and 48 V DC microgrids for domestic electrification projects, school etc.

Selecting a suitable rural area in Sri Lanka where access to the utility grid is not economically
feasible.
