The Impact

Electrical and thermal loads of residential buildings present a unique opportunity for onsite power generation, and concomitant thermal energy generation, storage, and utilization, to decrease primary energy consumption and carbon dioxide intensity. This approach also improves resiliency and ability to address peak load burden effectively. Demand response programs and grid-interactive buildings are also essential to meet the energy needs of the 21st century while addressing climate impact. Given the significance of the scale of building energy consumption, this study investigates how cogeneration systems influence the primary energy consumption and carbon footprint in residential buildings. The impact of onsite power generation capacity, its electrical and thermal efficiency, and its cost, on total primary energy consumption, equivalent carbon dioxide emissions, operating expenditure, and, most importantly, thermal and electrical energy balance, is presented. The conditions at which a cogeneration approach loses its advantage as an energy efficient residential resource are identified as a function of electrical grid’s carbon footprint and primary energy efficiency. Compared to a heat pump heating system with a coefficient of performance (COP) of three, a 0.5 kW cogeneration system with 40% electrical efficiency is shown to lose its environmental benefit if the electrical grid’s carbon dioxide intensity falls below 0.4 kg CO2 per kWh electricity.

The Impact

In future power systems, a large share of the energy will be generated with wind power plants (WPPs) and other renewable energy sources. With the increasing wind power penetration, the variability of the net generation in the system increases. Consequently, it is imperative to be able to assess and model the behavior of the WPP generation in detail. This paper presents an improved methodology for the detailed statistical modeling of wind power generation from multiple new WPPs without measurement data. A vector autoregressive based methodology, which can be applied to long-term Monte Carlo simulations of existing and new WPPs, is proposed. The proposed model improves the performance of the existing methodology and can more accurately analyze the temporal correlation structure of aggregated wind generation at the system level. This enables the model to assess the impact of new WPPs on the wind power ramp rates in a power system. To evaluate the performance of the proposed methodology, it is verified against hourly wind speed measurements from six locations in Finland and the aggregated wind power generation from Finland in 2015. Furthermore, a case study analyzing the impact of the geographical distribution of WPPs on wind power ramps is included.

This study evaluates potential aggregate effects of net-zero energy building (NZEB) implementations on the electrical grid in simulation-based analysis. Many studies have been conducted on how effective NZEB designs can be achieved, however the potential impact of NZEBs have not been explored sufficiently. As significant penetration of NZEBs occurs, the aggregated electricity demand profile of the buildings on the electrical grid would experience dramatic changes. To estimate the impact of NZEBs on the electrical grid, a simulation-based study of an office building with a grid-tied PV power generation system is conducted. This study assumes that net-metering is available for NZEBs such that the excess on-site PV generation can be fed to the electrical grid. The impact of electrical energy storage (EES) within NZEBs on the electrical grid is also considered in this study. Finally, construction weighting factors of the office building type in U.S. climate zones are used to estimate the number of national office buildings. In order to consider the adoption of NZEBs in the future, this study examines scenarios with 20%, 50%, and 100% of the U.S. office building stock are composed of NZEBs. Results show that annual electricity consumption of simulated office buildings in U.S. climate locations includes the range of around 85 kWh/m2-year to 118 kWh/m2-year. Each simulated office building employs around 242 kWp to 387 kWp of maximum power outputs in the installation of on-site PV power systems to enable NZEB balances. On a national scale, the daily on-site PV power generation within NZEBs can cover around 50% to 110% of total daily electricity used in office buildings depending on weather conditions. The peak difference of U.S. electricity demand typically occurs when solar radiation is at its highest. The peak differences from the actual U.S. electricity demand on the representative summer day show 9.8%, 4.9%, and 2.0% at 12 p.m. for 100%, 50%, and 20% of the U.S. NZEB stocks, respectively. Using EES within NZEBs, the peak differences are reduced and shifted from noon to the beginning of the day, including 7.7%, 3.9%, and 1.5% for each percentage U.S. NZEB stock. NZEBs tend to create the significant curtailment of the U.S. electricity demand profile, typically during the middle of the winter day. The percentage differences at a peak point (12 p.m.) are 8.3%, 4.2%, and 1.7% for 100%, 50%, and 20% of the U.S. NZEB stocks, respectively. However, using EES on the representative winter day can flatten curtailed electricity demand curves by shifting the peak difference point to the beginning and the late afternoon of the day. The shifted peak differences show 7.4%, 3.7%, and 1.5% at 9 a.m. for three U.S. NZEB stock scenarios, respectively.

This report aims to analyze the impact of state grants upon the effectiveness efficiency of the enterprises in the Agricultural sector. The presence/absence of the correlation between the “received state grants - financial results from the activity of the agricultural enterprises” was studied. The efficiency of agricultural enterprises is expressed through the indicators of profitability and productivity. The empirical data for a period of 10 years 2008 – 2017 were shown in the study. The main activities of the surveyed enterprises are crop, livestock and combined - crop-livestock. Based on the results obtained, it is expected that the receipt of grants will have a positive influence on the performance of enterprises in the agricultural sector, measured by indicators of effectiveness and productivity. The following research hypotheses have been proved: the positive effect of the grant is more obvious in larger agricultural enterprises, which have higher productivity and profitability compared to small and medium-sized farms; agricultural enterprises which receive grants and are characterized by higher investment activity and are also characterized by higher innovation activity; based on the predominant number of crop enterprises, it is assumed that this type of activity leads to the achievement of higher financial results as a result of the activity of the agricultural enterprises; the age of the enterprises, expressed through the years of their activity, contributes significantly to higher profitability and productivity of the carried out activity.

The article studies the role of marketing management in the activity of agricultural enterprises. The agricultural sector is one of the key sectors of the Ukrainian economy, the core component of which is agricultural production. The findings of the article show the fact that a significant number of agricultural enterprises are unprofitable, with their share in the total number of enterprises accounting for 13.3%. Their performance largely depends on the impact of the extremely complex, dynamic and uncertain environment. The article suggests that only the businesses possessing the ability of adequate adjustment to the environment with taking precautions against negative effects timely and using opportunities the fullest ensure their competitiveness and profitability of their activity in the long run. The article determines marketing management tools to be relevant for ensuring successful operation of agricultural enterprises under modern conditions, for there is a need to find new approaches to managing enterprise activities. The article reveals the essence of marketing management; offers the interpretations of the concepts of "marketing management" and "management of marketing" given by the Ukrainian scientists and foreign researchers; and studies the difference between them. The article suggests that marketing management is a broader concept than management of marketing due to the fact that it is management of all general and individual functions of enterprise, as well as all divisions of enterprise on the basis of marketing. Marketing management considers marketing and management inseparably - they also mutually penetrate and complement each other. The main goal of marketing management is to increase profitability of enterprise by achieving maximum customer satisfaction. Based on the generalization of different views of scientists, the main stages of a marketing management process at agricultural enterprise are identified and characterized, including analysis of internal and external environment, selection of target market segments, marketing strategy formation, marketing complex development, organizational structure construction, marketing management program formation and marketing management control and analysis. The process of marketing management at agricultural enterprise contains a number of specific procedures aimed at research and formation of the demand of target consumers and comprehensive satisfaction of their needs. The findings of the research prove that the use of marketing management tools will help ensure the market orientation of agricultural enterprise, which provides a focus on success, timely adaptation to the environment, gaining a leading position in the market, providing competitive advantage.

Domestic agricultural enterprises do not have a high level of innovation activity, however, stable and competitive operation of an agricultural enterprise is impossible without its innovative activity. Stabilization of the situation in the agricultural sector with the current level of competition and constant technological variables, the innovative vector of development is the driving component of economic growth. Activation of innovation of domestic agricultural enterprises is one of the important prerequisites for stability and sustainable socio-economic development of the country. Consequently, the effective functioning of the livestock industry is possible only under the conditions of systemic and purposeful innovation aimed at finding a variety of new opportunities provided by the business environment. The innovation process in domestic animal husbandry is clearly aimed at the end result - a certain socio-economic, technical or environmental effects. The efficiency of animal husbandry is determined after the introduction of innovation, calculated by the method of evaluation of investment projects. On the example of Lviv region we analyzed the conditions of innovative activity in animal husbandry, assessed the modern innovative potential of the industry, established the features of its innovation and investment activities. SWOT-analysis is an important component of assessing the position of livestock enterprises in the region. It should be recognized that the innovative activity of livestock enterprises is mainly associated with the final stage of the innovation process – the development of innovations. In 2020, farms of all categories of Lviv region compared to 2019 decreased meat production (sales for slaughter of farm animals in live weight) by 1.6 %, milk – by 4.7 %, eggs – by 0.3 %. cattle on farms of all categories on January 1, 2021 amounted to 144.4 thousand heads (including cows – 86.2 thousand heads), pigs – 346.1 thousand heads, poultry – 10.5 million. heads. Compared to January 1, 2020, the number of poultry increased by 5.7 %, pigs – by 4.1 %, the number of cattle decreased by 8.2 % (including cows – by 8.6 %). Innovative activity of the livestock industry is formed under the influence of the domestic innovation system and has its own specifics, which is caused by the peculiarities of agriculture. Most innovative projects are aimed at introducing innovations that contribute to the intensification of animal husbandry and increase the competitiveness of products. Thus, on the basis of innovative development of animal husbandry it is possible to achieve a significant increase in the competitiveness of agricultural enterprises, which will allow Ukrainian producers to achieve significant results in world markets for agricultural products.
