This paper discusses possible integration of demand side resources in electricity markets as a demand response program. To explore the technical feasibility of demand response (DR) programs and technologies, we performed a preliminary analysis of load impact by a couple of demand responsive technologies in air-conditioning, lighting and computing appliances for commercial building sector in the Tokyo...
The economic evaluation of the microgrids is still challenging. This paper presents a methodology to design the number and capacity for each piece of equipment (e.g. gas engines, batteries, thermal storage tanks) in a microgrid with combined heat and power (CHP) system. In the methodology, annual cost is minimized by considering the partial load efficiency of a gas engine and its scale economy, and...
A cooperative control system for gas engine generators and a lead-acid battery in a microgrid was developed. The control system enables a microgrid system to balance the electric power demand and supply and to simultaneously control the state of charge (SOC) of the battery. To evaluate this control system, we simulated its performance in balancing the control of an experimental microgrid facility...
This article outlines the ongoing research, development, and demonstrates the microgrid operation currently in progress in Europe, the United States, Japan, and Canada. The penetration of distributed generation (DG) at medium and low voltages is increasing in developed countries worldwide. Microgrids are entities that coordinate DERs (distributed energy resources) in a consistently more decentralized...
