Business Approach

In this paper, we show the preliminary results in a proposed a model for the supply and demand of electricity in a domestic market based on system dynamics. Additionally, the model indicates piecewise smooth differential equations arising from the diagram of flows and levels, using dynamical systems theory for the study of the stability of the equilibrium points that have such a system. A bifurcation analysis approach is proposed to define and understand the complex behavior. Until now, no work has been reported related to this topic using bifurcations criteria. The growing interest in personal ways of self-generation using renewable sources can lead the national grid to a standstill and low investment in the system. However, it is essential to preserve the national network as a power supply support to domestic and enterprise demand. To understand this scenario, we include an analysis of zero-rate demand growth. Under this hypothesis, a none smooth bifurcation appears related to a policy which involves the variation of the capacity charge. As a first significant result, we found that it is possible to preserve the investments in the market since, through the capacity charge parameter, the system dynamics can be controlled. Then, from a business approach, it is necessary to know the effects of the capacity charge as the strategic policy in the system generation price scheme.

Technical And Economic Indicators

The article discusses an original solution for designing an algorithm for selecting the most optimal technical and economic indicators for the operation of generating equipment of thermal power plants, taking into account the requirements of the wholesale electricity market, the day-ahead market and the balancing market. To design an algorithm for controlling generating equipment, the activity of a generating company in the wholesale electricity market was considered in terms of system dynamics. The proposed solution made it possible to select and interpret the state variables of the model, build flow diagrams describing the functioning of a technical-economic system, and visualize cause-and-effect relationships in the form of structured functional dependencies. In this work according to the norms of industry legislation and previously conducted scientific research the most important parameters were identified that form the flows of a dynamic technical and economic system, which are optimization criteria in fact. On the basis of this data, a stream stratification of the production processes of generating companies was carried out and a complex of mathematical models of system dynamics was developed to determine and plan the financial efficiency of the operation of thermal power plants and generating companies. The mathematical apparatus and the algorithm of its functioning are developed on the basis of the digraph of cause-and-effect relationships between the investigated technical and economic indicators. On the basis of the graph of interrelationships of system variables, a system of nonlinear differential equations has been built, which makes it possible to determine planned performance indicators when various technical and economic conditions change. The novelty of the proposed approach is the use of new model solutions based on the mathematical apparatus of system dynamics to represent the proposed model in simulation systems, in industry ERP and MES systems, for the development of DDS.

Electricity Saving

In case of opening the electricity market, various factors interact with each other. Although research has been done on various factors affecting the liberal electricity market, little attention has been paid to studying the dynamic relations between the actors involved in the liberal electricity market and projections on electricity consumption in households. The main aim of the research is to explore both short- and long-term effects on the electricity consumption at liberal market conditions by modelling various development scenarios. The electricity market in operation in Latvia was used as the case study. For the simulation of electricity market liberalization, system dynamics has been chosen. This method can determine electricity savings in case of electricity market opening, because system dynamics allows conducting simulation of complex systems and analysing the obtained data to forecast probability of the development of several scenarios. Obtained results show that cumulative electricity savings in households could reach 560 GWh by the end of 2020 due to the opening of the electricity market, implementation of energy saving measures and other reasons. In case of scenario analysis using the change of consumption behaviour, it was obtained that the cumulative electricity saving could be almost twice as big if the majority of households were guided by the environmental concerns. Although the system dynamics model was based on the Latvian case study, its general application to other countries and electricity markets is also possible.

When different stakeholders work together, they can implement a strategy to improve the performance of the electricity industry. This chapter shows how the cooperation and reputation influence on the electricity industry. A simulation model was developed to illustrate how related variables such as altruism, reputation, and strategic alliances contribute to promote the renewable energy industry. To do this, the chapter illustrates a case study for the electricity market in Colombia. The results show a novel perspective that contributes to marketers and engineers in the analysis of the relationship between cooperation and reputation in electricity firms.

Objective - This paper aims to investigate the feasibility of employing nuclear power in peninsula Malaysia, within the context of a deregulated electricity market framework. Methodology/Technique - System dynamics modelling and simulation has been adopted in this research. A qualitative causal loop diagram, which represent the relationships of key factors in the dynamics of nuclear power in peninsula Malaysia's electricity market, was first constructed. It is divided into three sections: (1) investment decisions, (2) power generation, and (3) maintaining business as usual. The causal loop diagram is converted into stock and flow diagram, where variables are quantified by input values and equation before simulated for a set period of 38 years. Three scenarios were designed to facilitate the research: (A) business, as usual, (B) nuclear power expansion, and (C) renewable energy expansion. Findings - Simulations showed that scenario B can potentially strengthen the region's energy security under specific conditions in addressing capacity redundancy and emissions reduction. Also, having a diverse market is paramount in contributing to the responsiveness of the market. Novelty - A systemic and dynamic understanding of the implications of two energy scenarios on the country has been established. Type of Paper: Empirical Keywords: Energy Security; Electricity Market; Deregulation; System Dynamics; Nuclear Power.
