Design Considerations of PV Water Pumping and Rural Electricity System (2011) in Lower Myanmar
Photovoltaic (PV) systems provides a viable means of
power generation for applications like powering residential
appliances, electrification of villages in rural areas, refrigeration and
water pumping. Photovoltaic-power generation is reliable. The
operation and maintenance costs are very low. Since Myanmar is a
land of plentiful sunshine, especially in central and southern regions
of the country, the solar energy could hopefully become the final
solution to its energy supply problem in rural area.

Coordinated Design of PSS and STATCOM for Power System Stability Improvement Using Bacteria Foraging Algorithm
This paper presents the coordinated controller design of static synchronous compensator (STATCOM) and power system stabilizers (PSSs) for power system stability improvement. Coordinated design problem of STATCOM-based controller with multiple PSSs is formulated as an optimization problem and optimal controller parameters are obtained using bacteria foraging optimization algorithm. By minimizing the proposed objective function, in which the speed deviations between generators are involved; stability performance of the system is improved. The nonlinear simulation results show that coordinated design of STATCOM-based controller and PSSs improve greatly the system damping oscillations and consequently stability improvement.
