Energy demand management

Summary

Energy demand management, also known as demand-side management (DSM) or demand-side response (DSR), is the modification of consumer demand for energy through various methods such as financial incentives and behavioral change through education. Usually, the goal of demand-side management is to encourage the consumer to use less energy during peak hours, or to move the time of energy use to off-peak times such as nighttime and weekends. Peak demand management does not necessarily decrease total energy consumption, but could be expected to reduce the need for investments in networks and/or power plants for meeting peak demands. An example is the use of energy storage units to store energy during off-peak hours and discharge them during peak hours. A newer application for DSM is to aid grid operators in balancing variable generation from wind and solar units, particularly when the timing and magnitude of energy demand does not coincide with the renewable generation.

Massive 3D models and physical data for building simulation at the urban scale

José Ramón Vazquez Canteli

In a time when governments are pursuing increasingly ambitious energy efficiency goals, building energy simulation at the urban scale, combined with the high availability of physical data, can help in performing this task. The purpose of this study is to describe the methodology used to create a geometrical 3D and physical model for the city of Geneva, and to analyze the energy-saving potential of several refurbishment measures, including the installation of more solar PV panels, for different climatic scenarios. Different sources of data are used to build a PostgreSQL database with the physical and geometrical characteristics of the buildings. The virtual models are simulated with CitySim, a program that estimates the energy demand for heating, cooling, and lighting of every building on an hourly basis. The models include, but are not limited to, the shadowing effect among the buildings, the passive solar gains through glazing, the internal gains due to occupants’ activities, the solar reflectance and infrared emissivity of the surfaces, and the materials that provide the buildings with insulation from the outdoors. This research will also provide some results that can be used by the municipal authorities of Geneva as a reference to quantify the decrease of the energy demand that they can expect to achieve in the next years.

This study evaluates the impact of urban planning decisions regarding building stock on energy system design and operation. Three urban planning scenarios are considered for an archetype neighbourhood in Nablus in Palestine. The distinguishing difference is that they have different albedo values for the building stock. A computational platform that combines building simulation, urban climate and energy system optimization (considering Net Present Value (NPV) and Grid Integration Level) is used to assess the scenarios. The study reveals that the annual or peak energy demand is not sufficient to compare two scenarios; it is important to consider energy demand pattern and the renewable energy potential, where an energy system design tool is important. Therefore, it can be concluded that the energy system design tools will play a major role in sustainable urban planning processes.

The Optimized Integration of Biomass Fuel in the District Heating System in Poznan, Poland: Part 2

Energy demand continuously increases what contributes to higher emissions of GHG. Moreover, the primary energy sources like coal, natural gas and oil are depleting. To manage this problem, the scientists have worked on the different possibilities of renewable energy conversion technologies in order to get the most useful and cleanest type of energy. In this work, there are investigated possible biomass conversion technologies in order to satisfy energy demand for Poznan, the city in Poland. Actually, the energy demand is met by coal combined with heat and power plant (CHP). There is an interest of changing actual coal CHP plant with biomass to minimize emissions. The aim of this work is to choose the best thermo-chemical biomass conversion option in the concept of minimum investment cost. To achieve this goal, the thermo-economic analysis and optimization of different biomass conversion technologies have to be conducted. First, on the basis of the literature review, the models of biomass conversion processes are modeled in Belsim Vali software. Then, from 2008, two different scenarios of energy demand are defined for the city. In the next step of this work, there is conducted energy integration in order to find an optimal set of designed boundary conditions through maximizing the units of performance for the most promising types of biomass conversion processes. Finally, an optimal configurations and sizes of the equipments are found by thermo- economic optimization.
