While environmental and energy concerns have become global issues, the government of South Korea has made notable efforts and formulated plans for the diffusion of renewable energy generation facilities for the nation’s public and governmental institutions. Accordingly, Jeju Island has become one of the most promising locations for utilizing renewable energy resources. This study aims to propos...

concepts of power engineering and electrical design dating from the late 1800s. Power flows from large-scale generating plant through high-voltage transmission and lower-voltage distribution networks before being delivered to consumers. This system is used throughout the world with great success, and is an essential enabler of modern living. Recently however, both government policies and market...

fixed feed-in tariff An offer by government or a utility to purchase electricity from renewables producers at a fixed price, regardless of the producers’ costs of production. green (renewables) certificate A certificate, provided by a regulator to renewables producers for specified units of their electricity output; can be traded to other electricity producers who need it to meet their obligati...

This paper is the second of a two part study that analyses the technical and financial performance of particular, recuperated engine systems. This second paper examines the financial performance of two hybrid (renewable/fossil), chemically recuperated power plants. One of these plants uses the combustion of biomass as the renewable energy input. The other assumes that solar thermal energy is us...

Renewable electricity policies promote investment in renewable electricity generators and have become increasingly common around the world. Because of intermittency and the composition of other generators in the power system, the value of certain renewables—particularly wind and solar—varies across locations and technologies. This paper investigates the implications of this heterogeneity for th...

This paper proposes a novel hybrid Monte Carlo simulation-genetic approach (MCS-GA) for optimal operation of a distribution network considering renewable energy generation systems (REGSs) and battery energy storage systems (BESSs). The aim of this paper is to design an optimal charging /discharging scheduling of BESSs so that the total daily profit of distribution company (Disco) can be maximiz...

Optimization of energy production systems is a relevant issue that must be considered in order to follow the fossil fuels consumption reduction policies and CO2 emission regulation. Increasing electricity production from renewable resources (e.g., photovoltaic systems and wind farms) is desirable but its unpredictability is a cause of problems for the main grid stability. A system with multiple...

This paper proposes two types of new auziliary ory. The first t y p e of the auxiliary matching store achieves high matching rate b y combining the LRU replacement algorithm and a simple match structure together. The second one achieves high match rate b y controlling strictly the number of active processes with an explicit hardware. Owing to some special characteristics of dynamic dataflow com...

Wind energy has been well recognized as renewable resource in electricity generation. In this paper, a novel hybrid approach is proposed for wind speed forecasting in a Rostamabad in Iran, from 2002 to 2004. The proposed approach is based on the combination of particle swarm optimization and adaptive-network based fuzzy inference system (PSO-ANFIS). The 10-minute average wind speed data from Ro...
