High Energy Consumption

В нашей стране затраты на топливо и энергию составляют от 10 до 40% себестоимости продукции. Такой высокий уровень энергоемкости увеличивает затраты предприятия, связанные с производством продукции, и, как результат, снижает его конкурентоспособность. Поэтому реализация энергосберегающих программ на промышленных предприятиях становится первоочередной задачей. Стратегическое управление энергоэффективностью позволит поэтапно оптимизировать работу и значительно сократить расходы предприятия. В статье проведены анализ и оценка активности промышленного предприятия АО «Себряковцемент» с учетом оценки энергоемкости его деятельности. Для развития существующей системы управления энергозатратами промышленного предприятия предложена модель на основе стандарта ИСО. In our country, the cost of fuel and energy is from 10 to 40% of the cost of production. High energy consumption of products should be recognized as the main problem, due to the fact that it has an impact on increasing the cost of production and, as a result, on reducing the competitiveness of enterprises. Therefore, the implementation of energy-saving programs at industrial enterprises becomes a priority. Strategic management of energy efficiency will allow you to gradually optimize the work and significantly reduce the costs of the enterprise. The article analyzes and evaluates the activity of the industrial enterprise of company «Sebryakovcement», taking into account the assessment of the energy intensity of its activities. In the development of the existing energy management system of an industrial enterprise, a model based on the ISO standard is proposed.

Energy management system is one of the challenging tasks associated with residential buildings. The cost of energy is purely based on the amount of energy consumed during peak hours. This paper focuses on an efficient energy management system for the control of energy consumption during peak hours. ZigBee module is used to monitor the energy consumed by the home appliances. The working of the proposed system is categorized into two modes of operation: normal time and peak time. During normal time, all home appliances can be operated and the cost of energy will be at normal rate. Whereas, during peak time, high rating machines will be shut down, that is controlled by ZigBee and the light loads will be operated from battery supply. Thus the proposed system reduces the energy consumption and is cost effective. Simulation analysis is done using proteus software. Hardware model is also implemented which proves that the proposed energy management system improves the energy efficiency.

The Cost

The data of calculating the actual cost of production are widely used in production management at industrial enterprises, to monitor compliance with the standard cost of production adopted by the enterprise, to identify ways to optimize labor costs and material resources. The level of cost depends on the activity of an industrial enterprise in a market economy: the amount of profitability, the economic efficiency of its activities. The choice of the method of cost accounting and calculating the cost of production depends on the specifics of the technology and organization of production, as well as the requirements of the efficiency of enterprise management. Studying the formation of accounting information when calculating the cost of production by type of product, comparing the level of costs with the revenue received makes it possible to determine the economic efficiency of production. The purpose of this study is to identify the problems of forming accounting information when calculating the cost of production for making decisions to reduce costs. The implementation of the research goal is facilitated by the use of methods of comparative analysis, synthesis, and graphical method for visualizing the results obtained. When considering the cost calculation, attention is paid to the fact that in market conditions there is a need for detailed cost accounting and calculation of the cost of production. If we take into account that in market conditions, prices for products are formed as demand increases, and demand is influenced by external factors, then we can only influence the costs based on the cost calculation. The basis for making effective management decisions will depend on how reliable and to what extent the accounting information is formed. Costs are the main constraint on the profit of industrial enterprises, since the main strategic goal of any enterprise is the mechanism for increasing profits. The ability to achieve this goal is limited by the following internal factors: the complexity of the cost grouping, technological processes, and the impact on product quality. It is necessary to improve the information system, which is based on the data of primary documents, document flow and the order of cost grouping. The proposed measures will contribute to strengthening the control function of the management and, as a result, effective cost management.

An optimal power dispatch of a small-scale standalone microgrid for remote area power supply in Colombian territory is proposed in this paper. The power dispatch is generated by an energy management system based on a mixed-integer linear programming, which minimizes the cost of operating the microgrid while fulfilling the technical constraints of its elements. The energy management system solves an optimization problem using the algebraic representation of the generators and its constraints. Basic steady-state models of the generators are selected to solve the optimization problem. The small-scale microgrid is considered for a remote area power supply in Taroa, a small settlement in La Guajira, Colombia. The microgrid is composed of photovoltaic modules, a wind generator, a diesel generator, a battery bank, and residential loads. To validate the solution, the elements of the microgrids are parameterized with information from commercial equipment. Moreover, the power dispatch obtained with the proposed solution is compared with a power dispatch generated by a heuristic algorithm, which has been previously used to dispatch power in a small-scale standalone microgrid. Results show that the cost of operating the microgrid is minimized using the proposed optimization approach: a reduction of the operating cost equal to 25.5% of the cost imposed by the heuristic algorithm is obtained.

Building Energy Management

Energy efficiency is a key to reduced carbon footprint, savings on energy bills, and sustainability for future generations. For instance, in hot climate countries such as Qatar, buildings are high energy consumers due to air conditioning that resulted from high temperatures and humidity. Optimizing the building energy management system will reduce unnecessary energy consumptions, improve indoor environmental conditions, maximize building occupant’s comfort, and limit building greenhouse gas emissions. However, lowering energy consumption cannot be done despite the occupants’ comfort. Solutions must take into account these tradeoffs. Conventional Building Energy Management methods suffer from a high dimensional and complex control environment. In recent years, the Deep Reinforcement Learning algorithm, applying neural networks for function approximation, shows promising results in handling such complex problems. In this work, a Deep Reinforcement Learning agent is proposed for controlling and optimizing a school building’s energy consumption. It is designed to search for optimal policies to minimize energy consumption, maintain thermal comfort, and reduce indoor contaminant levels in a challenging 21-zone environment. First, the agent is trained with the baseline in a supervised learning framework. After cloning the baseline strategy, the agent learns with proximal policy optimization in an actor-critic framework. The performance is evaluated on a school model simulated environment considering thermal comfort, CO2 levels, and energy consumption. The proposed methodology can achieve a 21% reduction in energy consumption, a 44% better thermal comfort, and healthier CO2 concentrations over a one-year simulation, with reduced training time thanks to the integration of the behavior cloning learning technique.
