This paper aims to solve the economic dispatch problem of the 28-bus Nigerian power system using genetic algorithm. The power flow solution of the network is first obtained using Newton-Raphson technique; the solution thus obtained is used to determine the loss coefficients of the network. For this study, a forecasted load demand of 2000MW will be considered, MATLAB's genetic algorithm optimization toolbox is used to obtain the optimum generation level of each unit. The optimal power output of each scheduled generating units was obtained after 200 iterations at a minimal generation cost of ₦136,370.205/hr. A power loss of 11.32MW in the network was also obtained using Kron's loss formula.

Every conceptual framework requires several developmental stages such as prototyping, preproduction and production stages. This paper considers prototype developmental stage which entails design, modelling and simulation for the conceptual system to determine suitable parameters and specifications before the production task is initiation. The inability to represent the conceptual control system with mathematical equivalence would hamper on the system operational efficiency, stability, controllability and observability; would not be guaranteed. This paper focuses on the modelling and simulation of intelligent master controller for hybridized power pool deployment. This is achieved using state space mathematical model, MATLAB/Simulink and proteus software. The state space model provides the mathematical equation for the system stability, controllability and observability criteria from the system transfer function. The MATLAB/Simulink software provides response trends and the Proteus software provides the virtual implementation platform for concept validation with its code written in Arduino (IDE). The system was demonstrated through simulation and the virtual results showed that the system capability in fostering intelligent control commands in the hybridized power pool scenario. The system stability was determined using Root locus, Nyquist and Routh Hurwitz criteria. Subsequent research efforts are being made towards implementing the design optimizable on the hardware using the design specifications.

The design of a power pool scheme for demand-side management of co-located banks in Owerri metropolis, Nigeria has been carried out in this work. The paper addressed the problem of matching instantaneous load demand with appropriate generator capacities which results from dynamic nature of small and medium scale industrial load, such as co-located banks. It also aimed at proffering solutions to health and environmental problems associated with use of scattered single generators per firm. A model for interconnection of generators and loads in a pool structure was developed to form a ring network, analogous to a typical power system. One of the generators in the pool was chosen as the slack bus and the other generators and load buses were arranged in the power pool arrangement such that Newton-Raphson's method could be applied in load flow analysis. With this modeling and application of appropriate schedule, a cooperative pooling model was developed such that only the exact generating capacities were deployed. The proposed model was simulated by paralleling three 200kVA generator units in a synchronized ring network to serve the entire five banks. Results from the load flow analysis showed that the per unit voltage magnitudes at buses 1, 2, 3, 4 and 5 were 1.000, 0.997, 1.000, 0.998 and 1.000 respectively, while voltage mismatch angles (degree) were also gotten as 0.000, 0.003, 0.024, 0.060 and 0.086 respectively for the buses 1 to 5. From the cost benefit analysis carried out, the benefit-cost ratio (BCR) of 1.965 was calculated, which showed that this project will be very beneficial to the cooperating banks. Scheduling the operations of the three generators using mathematical permutation and combination model showed that the total man-hour of the plant operators is reduced by 40%. Also, applying the greenhouse gases emissions cost model it was found that the carbon footprints i.e. greenhouse cost for the interconnected network is reduced by 40%.

This study presents the conceptual Android applications model for the smart micro-grid power pool monitoring and control scheme. The rational for energy sustainability is the focus of this research. Several hybrid formations are utilized on either standalone or off grid basis without formidable measures to monitor and control the system against energy wastage remotely. This research work proposed smart micro-grid integrated scheme with android enable operated soft-touch human machine interface for the remote monitoring and control of the hybrid power pool system with its load shedding capability for energy sustainability. The optimize hybridized renewable energy resources harvested from the abundant wind, sun, water and bio-resources with the grid and generator sources from afikpo local government area of Ebonyi state was considered as a research focal point. Proteus was used in designing system circuitries for the control and monitoring of the power pool system to ascertain its functionability. Arduino IDE was used in developing, monitoring and control algorithm for the system operation. The sublime text enables HTML, JAVA and CSS program for the android application implementation. The design provides a remote operated touch screen human machine interface for the pool resources to be centrally manage or control thus, eliminating energy wastage. Five communities where selected for this demonstration. The results reveal that the android enable remote soft touch human machine interface facilitates optimal energy operation. Further research work should be tailored towards developing a similar scheme using same approach for up to 10 communities in the similar local government areas to face out energy sabotage.
