Abstract:
Multi-agent based small scaled smart grid reinforcement scheme is proposed to manage
the energy resources by enhancing resilience to supply power to critical load in the event
of peak demand, by leveraging demand response program to optimize consumption
pattern in the response of grid cost and interconnected multi-microgrid comprises of
diverse energy resources solar, wind, storage system and diesel generator allow sharing
energy to balance fluctuation in intermittent resources by deploying market system that
reward cheap energy to consumer within respective microgrids. Three stages are defined
in this proposed scheme. Firstly, without DER, consumption charges are being reduced to
7.1% through demand response program but customer comfort is compromised. In second
stage, MGs comprises of only RER, energy consumption related charges are reduced to
92.2% by feed-in tariff (FIT) program. In the final stage, with the inclusion of energy
market for trading at MCP among MGs resulting in reduced charges greater than charges
incurred from the grid is defined by 122.1%. Average carbon emission reduced from
interconnected MGs to 78.6% and therefore MGs are incentivized by carbon offset credit.
Integer linear programming based technique is applied to allow the optimal dispatch of
MG generation to reduce the operation cost to 42.64%. Appropriateness of the proposed
approach is tested by developing cases with the aid of simulation. Substantially desired
outcomes are attained via DRP, optimal storage scheduling and energy trading by way of
market regarding reduce reliance on grid, energy usage adjustment in the response of grid
cost and alleviate the requirement to purchase electricity at high prices. The results
demonstrate that both our greatest daily power consumption and the amount of electricity
we draw from the utility system have changed. More specifically, daily average import
has gone up to 205.3 kW from the previous 134.7 kW. Similar to how peak demand, which
was 591 kW previously, is now 495 kW. Significantly favourable results have resulted
from these adjustments, including better resource utilization, more efficiency in electrical
market trading, and a decrease in our bills.
