<p>A methodology is developed to study the interrelations between photovoltaics
(PV) and storage systems in the context of demand side management. This study
concentrates on the most prominent types of storage systems and photovoltaic
technologies, which are lead acid batteries and single crystalline silicon cells and
amorphous silicon cells, respectively. The methodology concentrates on the daily
operating cost of the system. Only from a detailed comparison of altenatives can we
develop a system that maximizes the benefits of photovoltaics and storage systems, while
remaining cost competitive. This methodology consists of several steps that include;
simulation runs to determine yearly energy production and consumption, life cycle
costing, and analysis of daily cost graphs. During the analysis several items including
photovoltaic and storage system technologies, different demand limits and demand
charges, and different amounts of load control and purchased electricity as well as
different PV and electricity costs are discussed, and the following conclusions are
reached.</p>
<p>
The type of photovoltaics used plays an important role in the system design. The
amorphous cells seem to have a lower performance degradation in cloudy or hazy
conditions, but single crystalline cells have a lower operating cost especially when there is high sunlight. The cost of photovoltaics also has a great effect on the daily operating
cost. By keeping the cost of photovoltaics low (around $2.00/watt), the overall daily
operating cost decreases while increasing the photovoltaic array size. This shows that
photovoltaics can have a positive economic benefit. The effect of battery cost and on the
daily operating cost is minimal. This is because its cost per day is a small part of the total
daily operating cost. On the other hand, the demand limit and demand charge greatly
effect the magnitude of the daily operating cost. The main component of the daily
operating cost is purchased electricity. The daily operating cost increases as the cost of
purchased electricity increases.</p> === Master of Science |
