The mixer is controlled through a Supervisory Control and Data Acquisition (SCADA) system and programmed using Ladder Logic in Siemens Step 7 PLC Programming Software. Temperature control, agitation control, and ingredient addition sequences were all integrated by the automated system. The performance of the modeled system is validated through computer simulations. The Batch Mixer is controlled using a Variable Speed Drive (VSD), enabling precise execution of the required processes throughout the entire mixing cycle. Each phase of the process is carefully controlled and monitored, with detailed simulation results demonstrating enhanced performance and efficiency in the proposed batch mixer system, as well as offering a mathematical model of the Batch Mixer and outlining the performance variables that the PLC systems use in detail. As a backup validation tool, Rockwell Automation's RSLogix 5000 PLC is used to verify the validation. The study demonstrates the effectiveness of using Siemens STEP 7 PLC for automation and validation, and with RSLogix 5000 PLC for confirmation of validation, ensuring reliable and efficient pharmaceutical batch mixing operations.

This paper brought to the fore the historical background of wind energy. There are some concerns when generating electricity from wind energy source. This paper disabused some of the concerns and projected the advantages and benefits of generating electricity from wind energy source. The paper also discussed the construction of wind power systems and the components that made up this plants. Harnessing this energy could be done from wind farms, this write up described the types of wind farms: onshore and offshore wind farms. The paper revealed the characteristics of wind energy that could facilitate the generation of electricity from wind source. To prove the suitability of generating electricity from wind energy, the paper tabulated some of the countries in the world that generated significant amount of electricity from this source. The paper also described in depth the perspective of Ghana in the generation of electricity from wind energy. The paper discussed data obtained from Energy Commission of Ghana and settled on eight locations or sites for analysis. The mathematical expressions and equations that encompassed generation of electricity from wind energy source were deliberated on extensively in this write up. The article also brought to the fore the technical and geographical wind potentials of Ghana and modelled mathematically the available power from the output of wind turbines. The carbon dioxide emission that could be reduced by Ghana from this research was also discussed.

This goal is however not easily attained, especially in Sub-Saharan African countries and across many developing nations due to the lack of capital, sufficient generation capacity to meet growing loads, aged or dilapidated transmission and distribution infrastructure, high supply costs, coupled with the weak financial position of utilities and their inability to recover revenue from low-income households as well as high line losses. In this paper, a PV-Wind-Battery hybrid renewable energy system is designed to meet the energy needs of Ayitepa, a typical fishing and farming community located within the Ningo-Prampram district, about 63 km from the capital Accra with a population of 1,375 people, residing within 194 households in 138 houses. The community's daily electrical load was estimated to be 100 kW, with a cumulative daily primary load of 180 kWh/d consisting of residential, commercial, and industrial loads such as houses, schools, flour mills, a health clinic, and cold stores. HOMER software was used to perform analysis to determine the optimum hybrid renewable energy system configuration for the community. It was observed that the configuration comprising a battery bank (3,050 kWh), converter (66 kW), PV (180 kW), and wind turbine (50 kW) was the best configuration sizing required to meet Ayitepa's load. The hybrid system LCOE
