179-182

In General residential sectors are the major consumers responsible for the peak load in Iran. However, the consumer satisfaction in residential area is important but there needs a method to control the peak load by using smart load controllers. In this work, a load control system is designed and applied in relation with the Iranian Social structure to reduce the intensity of the peak load.

W artykule analizuje się komunalną sieć zasilania energią elektryczną. Na przykładzie takiej sieci w Iranie proponuje się metody zapobiegania przeciążeniom sieci.

Demand Side Management and its Possibilities in Jordan

The increase in energy consumption and energy bills in Jordan have been escalating rapidly, which requires a special concern as a large percent of the energy is imported. The need for the reducing peak demand of the distribution network is essential to decrease the overall electricity generation cost. This study was aimed at presenting a model for a home that manages its energy consumption, and the maximum savings possible if the load shifting to off-peak times was applied. It also introduced a tariff that is more concerned in time of use rather than consumption only. The power consumption profile is collected for a sample house. The profile for a week was registered and graphed. The pricing suggested was calculated per day. Moreover, some samples applied worldwide were discussed to find a suitable model. It was found that a saving rate of 16% is achievable if the time of use charge is applied. Additionally, a peak load reduction of 3.5 kWH average per day (in the peak hours) is possible.

Reflections on smart grids

The discussions on the energy transition, the involvement of households as decentralized energy providers and the reduction of energy costs show an area of conflicts, in which they act as driving force on Smart Grids. In this regard Smart Grids are seen as a key element to address the former mentioned challenges. This paper continues the public discourse concerning Smart Grids and displays it from various perspectives such as technique, professionalism, and communication. It is striking to note that for a long time the discussion has been customer-focused, but in regard to the realization of the energy transition and the power line problem, the energy providers came to the fore. Altogether, there is a lack of a clearly defined target and its matching steps. Here, policy makers in particular are required to specify a legal environment, which considers national as well as international conditions and facilities on the internationally affected grid.

Dyskusje na temat przekazywania energii i zaangażowania gospodarstw domowych jako zdecentralizowanych dostawców energii i redukcji kosztów energii pokazują obszar konfliktów, w których bardzo istotne są inteligentne sieci. W związku z tym, inteligentne sieci energetyczne są postrzegane jako kluczowy element sprostania wyzwaniom rynku. Niniejszy artykuł jest kontynuacją dyskursu publicznego dotyczącego inteligentnych sieci i przedstawia problem z różnych perspektyw, takich jak technika, profesjonalizm i komunikacja. Uderzające jest to, aby pamiętać, że przez długi czas dyskusja koncentrowała się na kliencie, ale w odniesieniu do realizacji transformacji energii i problemy linii energetycznej i dostawców energii również są bardzo istotne. Bardzo ważne jest w tym zakresie prowadzenie spójnej polityki w zakresie środowiska.

Stackelberg strategies for weighted load balancing games

An instance of a weighted Stackelberg load balancing game is given by a set of identical machines, a set of variable-length jobs and a parameter 0 ≤ α ≤ 1. A centralized authority, denoted the leader, selects a subset of the jobs whose total length is at most an α-fraction of the total length and determines their assignment on the machines. After the controlled jobs are assigned, the remaining jobs join the schedule. They act selfishly, each determining its own assignment. Our work combines theoretical and experimental results for this setting. We suggest various heuristics for the leader and analyze their performance.
