Energy management in grid-connected Micro-grids (MG) has undergone rapid evolution in recent times due to several factors such as environmental issues, increasing energy demand and the opening of the electricity market. The Energy Management System (EMS) allows the optimal scheduling of energy resources and energy storage systems in MG in order to maintain the balance between supply and demand at low cost. The aim is to minimize peaks and fluctuations in the load and production profile on the one hand, and, on the other hand, to make the most of renewable energy sources and energy exchanges with the utility grid. In this paper, our attention has been focused on a Rule-based energy management system (RB EMS) applied to a residential multi-source grid-connected MG. A Microgrid model has been implemented that combines distributed energy sources (PV, WT, BESS), a number of EVs equipped with the Vehicle to Grid technology (V2G) and variable load. Different operational scenarios were developed to see the behaviour of the implemented management system during the day, including the random demand profile of EV users, the variation in load and production, grid electricity price variation. The simulation results presented in this paper demonstrate the efficacy of the suggested EMS and confirm the strategy's feasibility as well as its ability to properly share power among different sources, loads and vehicles by obeying constraints on each element.

The Relationship

Aim. The presented study aims to develop and describe a contract management system for FMCG chain retailing companies in the context of the digital transformation of the economy.Tasks. The authors examine the specific aspects of developing a contract management system for chain retailing companies; develop a classification of contracts by sector of activity and outline the landscape of the contract management process; create and describe a system for managing contracts.Methods. The methodological basis of this study includes conceptual representations of the contract management system, which make it possible to apply a systems approach, generalization, grouping, methods of formal system representation, and socio-economic experimentation.Results. The study examines the specific aspects of developing a contract management system for chain retailing companies in the context of the digital transformation of the economy, describing the major types of contracts used by these companies. The contracts are classified by sector of activity, and the landscape of the contract management process is outlined. Its individual units correspond to the Deming cycle and represent a cyclically repeating decision-making process.Conclusions. As a result, a contract management system for chain retailing companies is proposed, and the relationship between the management subsystem and the system of requirements for the architecture of business services in the field of contract management is determined. It is shown that successful implementation of an efficient contract management system requires preliminary work to identify requirements for the architecture of business services. Taking into account these requirements in the modeling of architectural solutions and integrating them into the business architecture will ensure high-quality contract management through the optimization of the company’s resources and highly efficient regulation of the relationship between the stakeholders and counterparties of chain retailing companies.

Building projects with private ownerss have high level of payment issues (late payment, underpayment, or non-payment). The purpose of this study is to develop a risk-based contract management strategy to avoid late payment from private ownerss to contractors. The research data consisted of literature reviews, questionnaires, and qualitative risk data analyses. The risk analyses identified 10 highest risks as the dominant risk factors from 37 risk variables. The risk response to dominant risk variables was used as a strategy for developing a contract management system. Risks affecting late payment were largely due to contractual clause and contracting clients with less financial capacity due to lack of analysis in the pre-contract phase
