Abstract:
Although the demand for power is growing rapidly, it is not being met at the
same rate. Even though the generation capacity has reached 20 GW still,
significant power crisis is being observed due to unreliable power system
operation. Delivering power and energy at a lower cost is inevitable for efficient
operation of the electric power system. Increased energy consumption has
aggravated the issue of energy security, necessitating the usage of renewable
resources. Solar photovoltaic technology is one of the best strategies for
encouraging electricity generation from sources of renewable power in
Bangladesh. Grid-connected solar photovoltaic systems are becoming more and
more popular every day because of the growing amount of solar energy and the
declining ancillary prices of solar PV modules. Due to industrialization and
fourth industrial revolution electric demand is soaring high. As a result, thereby
a gap between demand and supply exist to solve this problem. This research
proposes technoeconomic operation of solar PV power integrated power system
optimization to optimise operation cost and selling price. A model for solar PV
integration has considered with south eastern PGCB grid. We have analysed the
techno economic benefit comprises of operational cost and selling price. A grid
power system with seven buses is tested using an ideal power flow method. The
prospect of injecting renewable power into one of the test bus systems is being
investigated. Conventional power plants use seven different kinds of fuel to
provide the load. Nine transmission lines connected each of these facilities. To
determine the system's optimality conditions, the Lagrangian technique and
Karush Kuhn Tucker (KKT) criteria are applied. To evaluate upcoming
operational costs and selling prices, a number of prospective case studies have
been simulated. Both with and without solar energy, the optimal power source,
vi operational costs, and selling price were evaluated. Despite a 60% increase in
load, a considerable amount of operating cost was decreased in 2041, accounting
for 72.22%.
