System Dynamics Modeling of Households' Electricity Consumption and Cost-Income Ratio: a Case Study of Latvia

At the scientific level it is being increasingly recognised that the concept of bioeconomy has transdisciplinary nature, but there is still no consensus on key factors that would accelerate the development of sustainable bioeconomy. Therefore, within the framework of this study, certain factors, their interactions and link strength with bioeconomy from a scientific perspective are identified. A bibliometric analysis method is used to achieve this aim in such a way that the keyword information on the published scientific literature in relation to the bioeconomy is translated into quantifiable data. This way the relevance of the bioeconomy factors and the strength of their direct and mutual interaction with the bioeconomy will be determined. From this study it can be concluded that the strongest links with bioeconomy are for biomass, bioenergy, biotechnology and innovations. No significant link was found for such factors as: behaviour, production, pollution and infrastructure. It becomes clear that, in the view of scientists, the decisive role in the development of the bioeconomy resulting from the use of bio resources in the higher value-added production is for technologies. These results are used to build a framework for a system dynamics model that can be used for modelling bioeconomy development scenarios in the future.

“…Environmental actions are crucial, but again, only through overall activities we can await the needed outcome o f improved urban health and environmental preservation. In this study, we contend that there is no substitute or recompense to the health, hence, the actual state of energy production is not the most effective pathway to the stability for basic load of energy [19], [20]. Based in the research data analysis of the environmental impact of coal power plants, the following crucial actions are needed:…”

Environmental and Climate Dilemma: Coal for Heating or Clean Air for Breathing: A Case of Prishtina

Bajçinovci

2019

Air pollution as a global issue is an essential health problem, faced by millions of people all over the world. It is a huge problem encountered by the citizens of the city of Prishtina, too. The benefit from the cheapest forms of energy, that generated from coal-fired power plants, and the one derived from the low financial cost, raises the question: do we have to compensate this energy with our health? This paper presents the analysis of the emanations, such are coal-fired power plants in the vicinity of the city of Prishtina, and aims to determine the accepted level and health framework boundaries for coal-fired power plants and coal processing activities. The research methods consist of empirical observations and data analysis on health degradation, environmental and greenhouse gas contribution to the climate change. The actual state of energy production is not the most effective pathway to the stability of basic load for energy. Hence, the debate focused around environment tends to fail the essential need for supplying Kosovo with electricity, something for which power plants are suitable. Unfortunately, with all our environmental stubborn beliefs, renewable sources such as sun and wind are not, in the present efficiency for Kosovo. The present hazardous air quality requires well defined lawful steps and activities. Thus, the research findings recommend and promote precise immediate environmental measures.

“…Efficiency is another management tool often related to load-shifting. A case study for household electricity consumption in Latvia considering the effect of growth of demand and energy efficiency due to the technological development is considered in [12].…”

The Merit-Order Effect of Load-Shifting: An Estimate for the Spanish Market

AbstractRenewable producers can offer selling bids with very low marginal cost since they are not obliged to include on any cost related to the use of energy from the wind or sun. Accordingly, when the Market Operator integrates a renewable bid in the merit-order generation curve, all the generators based on conventional technologies, with higher marginal cost due to the cost of fuels, are displaced to the right. The right-shifting of the merit-order generation curve leads to a lower clearing price, a small increment of the traded energy (almost inelastic demand curve), and a reduction of the total cost of the energy traded in the wholesale market. This is the key mechanism of the well-known merit-order effect of renewables. Load-shifting (demand-side management) plans are expected to yield a reduction of the cost of the traded energy for the customers, since the cost-saving due to the energy eschewed at peak hours would be greater than the extra cost due to the increased demand at off-peak hours. This work will show that the main effects of load-shifting on the market are qualitatively similar to that of renewables, which exemplify the existence a “merit-order effect of load-shifting”. To analyse the characteristics of the merit-order effect of load-shifting, a simplified model has been developed, based on the displacement of the generation and demand curves. A set of scenarios has been generated in order to quantify the main effects on the Spanish/Iberian market for 2015.
