Abstract:
As a result of technology development, expansion of
industries and improvement of living standards, the electricity
demand increases rapidly. It is the responsibility of the utility to
supply uninterrupted, reliable and good quality power to
customers. Basically, it is the balancing of supply against the
demand. Building new power plants to match the supply to
increasing demand may not always be economically viable. The
trend now is to control the demand with demand management
initiatives. This study evaluates the reasons for changes in day
peak and night peak in the electricity load profile, to study the
feasibility of making the load profile smoother using Demand
Side Management (DSM) initiatives. After analyzing several
types of customer categories, it was identified that Chilled Water
Storage (CWS) systems and Electrical Vehicles (EV) can make a
significant change in the load curve. By constructing storage
tanks to store chilled water during the off-peak tariff period,
and using the stored chilled water to meet the peak-time cooling
demand will reduce the demand at peak time. A mathematical
model was developed for demand forecasting, incorporating
DSM.
