This paper presents a multiobjective optimization method to jointly optimize the planning and operation of a grid-tied microgrid (MG) with various distributed generation sources such as wind turbine and photovoltaic arrays with the assistance of demand side management. In order to explore the economy and demand variety, the problem is formulated as a double-objective optimization to minimize the total...
In this paper, a Markov chain based model to generate household electricity power time series for the purpose of distribution grid planning is presented and evaluated. Based on statistical data, the equipment of each single household as well as the time depended behavior of each single appliance within a 15-minute resolution is simulated. Thereby, the households' equipment is based on the household...
In the new era of smart grid in power system, demand side management (DSM) plays a vital role which helps the customers to make the right decision regarding their power consumption thus minimize the peak load demand and provide the best load profile. Due to DSM carbon emission level and financial cost has been deduced. This paper represents a strategy on load shifting technique for demand side management...
Changes in the residential load warrant the investigation into more advanced planning methods for distribution grids. Smart grid alternatives require detailed information on network loading, and a risk based evaluation of different planning options, via a probabilistic approach. To limit the increased computational burden associated with this increased complexity, the required level of detail in modelling...
This paper quantitatively compares five demand response (DR) approaches for waterbeds using simulation. The approaches enable privacy by design with a local control and contribute to the planning phase of the electricity network's balancing process. Approaches are assessed by their energy consumption, their ability to shift power consumption to times of high availability, and the effort of realization...
This paper address the issues of surplus power that would happen when the sum of the generated power of Photovoltaic(PV) Generation Systems and minimal output of utility power plant exceeds total electricity demand that would affect the stable operation of power system. The cooperative control of customer's appliances such as Heat Pump Water Heater(HPWH) and battery is applied for utilizing surplus...
The present UK distribution network planning standard, Engineering Recommendation P.2/6 (P2/6), defines the acceptable durations of supply outages following first and second circuit outage conditions as function of group demand. In addition, P2/6 specifies a capacity value for distributed generation (DG) to be used in future circuit capacity planning. The approach does not consider other elements...
Due to increasing energy prices and the greenhouse effect, a more efficient energy supply is desirable, preferably based on renewable sources. To cope with the decrease of flexibility due to the introduction of renewables in production side of the supply chain, a more flexible consumer side is required. In literature, a lot of management methodologies are proposed to exploit the flexibility of consuming...
The deployment of advanced metering infrastructure has already started in many countries around the world in order to facilitate the transition towards low-carbon economies, to improve electricity billing, to decrease distribution network operational costs, and to empower householders. In addition, the adoption of photovoltaic panels, electric vehicles and smart appliances, already being encouraged...
Demand side management (DSM) can help reduce demand of the system, resulting in less generating capacity and less total production cost in the future. Generally, each DSM activity, e.g., replacing old with new higher efficiency equipment, has its own cost. Its worth in the system may be used as one of the decision components. Therefore, the methodology in evaluating the DSM worth under the framework...
This paper presents a Multi-Agent System (MAS) for Demand Side Management (DSM) in smart grid which uses an energy market for resource allocation. The multi-agent system contains Load Agents, Generator Agents and DSM Agent, which provides an electronic auction platform. The automation of the demand side management through the multi-agent system is equipped with an intelligent strategy which allows...
This paper publishes results of a recent study to design a software module to be implemented in dispatch centers of electric utilities which is capable of controlling certain aspects of power shortage among AMI residential subscribers. It proposes a new algorithm for modeling and managing of AMI subscribers during outage planning. In this study, a new index named consumption pattern merit is defined...
Based on the improved genetic algorithm, a wind biomass co-generation system (WBCS) planning model is put forward. The expansion plan which minimize the total cost is introduced to increase the reliability of Micro-Grid(MG) and meet the nonlinear constraints of system planning and operation. In the process of planning the total cost, not only the unit construction cost and operation cost are considered,...
In order to provide guidance in the planning process of energy efficient urban redevelopment projects and describe energy management strategies for existing neighborhoods the overall objective of the presented approach is to develop a methodology describing the energy balance of urban neighborhoods building on an integrated assessment of energy efficiency measures and efficient supply systems. A necessary...
This paper is to investigate the optimal substation capacity expansion problem for distribution system. The monthly energy consumption and the service types of all customers within each fence area have been retrieved from the customer information system in Taipower. The load demand of each fence area is calculated according to the typical load patterns and energy consumption of customers. The S curve...
This paper presents the effects of Demand Side Management (DSM) on the planning and operation of distribution grids. For this purpose the impact of DSM on the simultaneity function (also known as coincidence function) of electrical loads is taken into consideration. If there is a high DSM participation a distinct increase of the simultaneity factor can occur temporarily. The effects of an increased...
In order to keep a proper functional electricity grid and to prevent large investments in the current grid, the creation, transmission and consumption of electricity needs to be controlled and organized in a different way as done nowadays. Smart meters, distributed generation and -storage and demand side management are novel technologies introduced to reach a sustainable, more efficient and reliable...
During the high economic growth era in the world, the power of demand has been increasing sharply year by year. Therefore, the electric power utilities have installed Shunt Capacitors (SCs) for the predicted demand. Meanwhile, some SCs have become aged because they have been used for a long time. Therefore, they have to be replaced when they reach their life limit. It is important to renew aged SCs...
The growing environmental concerns and increasing electricity prices have led to wider implementation of demand-side activities and created a new class of consumers, called demand response resources (DRRs). The DRRs actively participate in the electricity markets as buyers of electricity and sellers of load curtailment services. The demand profile modifications resulting from the DRR curtailments...
According to Japanese governmental target, more than 50 GW will be penetrated on the whole utility system until 2030. Such large penetration of PV system may cause deterioration of power quality and stability of the whole utility grid. CRIEPI is promoting a study of future Japanese style smart grid called “Triple I (Intelligent, Interactive, Integrated) Power System (TIPS)” to keep stable and to promote...
