As modern control systems are becoming more complex, and the implemented technology more sophisticated, the importance of the different characteristics of those systems, such as reliability, availability, security, and protection, is increasing. In this article, an automation design for the air conditioning system of classified areas of the Parenteral solutions plant of the eastern pharmaceutical laboratory company of Santiago de Cuba province, Cuba, is proposed because there is a lack of optimal environmental conditions for development and production of pharmaceuticals at a large scale. The proposal is focused on the design of a supervision system and automatic control of the environmental variables that influence the drug production process. The entire algorithm for the design was developed to monitor critical and non-critical variables and control values of temperature, relative humidity, differential pressure, and air velocity according to standards established by pharmaceutical companies. The design of the automation system includes, apart from the control and supervision algorithm for operation efficiency, the necessary instrumentation.

The integration of renewable energies in the electric power system, as a solution to the growing demand for electricity in developing countries, has become a vital issue, such is the case of Mexico. The purpose of this work is the assessment of the economic and energy feasibility of a residential house grid-connected hybrid photovoltaic (PV)-wind system, in Mexico. The hybrid PV-wind system design is based on the existing renewable energy resources and considering a typical load profile. Also, an economic analysis is presented based on the two schemes approved for the sale of the surplus of the energy generated in Mexico: Net billing and net metering. The results obtained demonstrate the viability and profitability of the proposed small-size system. However, the results corroborate that government incentives are crucial to making the proposed system more attractive and affordable for residential users. La integración de energías renovables en el sistema eléctrico, como solución a la creciente demanda de electricidad en los países en desarrollo, ha convertirse en un tema vital, tal es el caso de México. El propósito de este trabajo es la evaluación de la viabilidad económica y energética de un residencial. casa sistema híbrido fotovoltaico (PV) -eólico conectado a la red, en México. El diseño del sistema híbrido fotovoltaico-eólico se basa en las renovables existentes. recursos energéticos y considerando un perfil de carga típico. Asimismo, se presenta un análisis económico con base en los dos esquemas aprobados para la venta de el excedente de la energía generada en México: facturación neta y medición neta. Los resultados obtenidos demuestran la viabilidad y rentabilidad del propuesto sistema de pequeño tamaño. Sin embargo, los resultados corroboran que los incentivos gubernamentales son cruciales para hacer más atractivo el sistema propuesto. y asequible para usuarios residenciales.
