Hybrid between PV and Generator with battery is one common technology that has been used in the world due to meet the system with the presence of renewable energy. These systems are typically used in isolated area or areas away from the grid. In this paper the hybrid PV-Generator with battery power plant will be designed for Aha Village in Morotai Island which is one island in Indonesia that located...
In this paper, we propose a frequency-based autonomous control strategy for an isolated microgrid with the grid-forming energy storage system (ESS) in the South Korean island of Geocha. This strategy uses a system frequency as a global data signal using a grid-forming ESS. The distributed generation (DG) units in the microgrid use the frequency as a control signal without communication because the...
Domestic installations traditionally were believed to be resistive in nature and did not affect power factor much, if at all. With increasing affordability of air-conditioners, and replacement of electrical geysers with heat pumps, loads are becoming more inductive. Small-scale renewable energy generation through e.g. solar photo-voltaic (PV) panels are becoming more affordable and as such are connected...
In this paper, multi-agent architecture was used to provide control for standalone microgrid with distributed generations. Therefore, to achieve a faster control compared to the centralized controller, each agent incorporated with a local prediction or forecasting model to provide anticipatory responses. To accomplish their common goals successfully, the agents cooperated based on facilitator architecture...
From the viewpoint of the emerging concept of smart grid, distribution network will require fast power flow solution that must be resolved as efficiently as possible. Presence of distributed generators and power electronic based compensating devices, in modern medium and low voltage distribution networks, additionaly expands requirements for performances of algorithms for power flow calculations which...
Distributed renewable energy sources progressively gain importance in power systems, with which new challenges, but also new opportunities, arise. Therefore, it is necessary to analyze the interaction between this type of generators and the grid, and to study adequate control methods that allow small generating units to operate harmoniously within power systems and contribute to their control, stability,...
This paper presents a new dynamic and stochastic decision supporting model for distributed generation investment planning (DGIP). The model is formulated as a mixed integer linear programming (MILP) optimization problem that simultaneously minimizes emission, operation and maintenance, as well as reliability costs. One of the salient features of the model is that it is based on a two-period planning...
With 1.3 billion people lacking access to electricity, the demand for power is increasing drastically. Electricity can no longer be considered a luxury, and is necessary for maintaining a modern life expectancy. This paper explores the feasibility of energy production and storage across South America, South East Asia and sub-Saharan Africa with National Renewable Energy Lab's Geospatial Toolkit and...
Energy from Waste (EfW) should be taken account as an alternative renewable resource for local energy generation in microgrids. This study theoretically demonstrates benefits of EfW plants for microgrids. Power flow simulation results were shown for a scenario of town grid with the population size of 115000. IEEE 9 Bus system is used to model distribution system of this town. 5 MW Energy from Waste...
Since the last decade, distribution networks are facing a continuously growing penetration of distributed generation, mostly thanks to the “clean energy” incentives promoted by national governments. In particular, these initiatives have enhanced the presence of renewable-based generators in electricity grids. Taking advantage of their intermittent nature, the curtailment of a small portion of production...
In this paper an optimization algorithm is applied on a microgrid with renewable energy and distributed generation. The intermittent electricity in Lebanon leads to widely use diesel generator groups and to install renewable energy in private places in order to cover the consumption during the power cut. The proposed case study consists of three energy hubs integrating renewable energy, diesel engines,...
The increase of renewable energy sources and distributed generation may have a negative impact on power systems, specially on weak ones. Therefore, their control systems are acquiring growing importance, with new proposals that aim to contribute to the control and stability of the power system as conventional generating units. This paper studies the effect that a PV system using a synchronous power...
Diesel generators account for the majority of generation into remote and off-grid power systems. However, complementary generation alternatives are increasingly becoming both available and cost competitive, specifically via the introduction of renewable technologies. Achieving optimal integration requires the diesel generators to be able to operate sustainably at low load levels. A key roadblock to...
This paper describes generic models of photovoltaic (PV) systems developed for implementation in Western Electric Coordinating Council (WECC) base cases. The scope encompasses both transmission-connected, central station PV plants and distributed PV systems. These models were added to the WECC Approved Dynamic Model Library in March of 2014.
Energy shortage is one of the major impediments to social, industrial and economic growths in developing countries. For instance, only about 40% of Nigeria's population (about 170 million) has access to electricity. Due to this, petrol/diesel generators are used for electricity generation in various sectors of the country, which are not eco-friendly. Though developing countries are thought to emit...
This paper presents a novel concept for increasing the penetration level of distributed renewable energy systems into the main electricity grid. When increasing the renewable energy penetration, it is important to implement the frequency based power delivery in distributed generators and work as traditional synchronous generators. This can be achieved by improving the power processing unit of each...
The surprising rates of electrification have experienced numerous populated counties in Asian region such as Bangladesh, Indian, China and Indonesia. To meet the increased demand for both power and grid services across the region will require innovation approach and the term discrete power system microgrid has introduced. As the reliability and quality of power demand have increased day by day, power...
As anaerobic digestion waste to energy systems become more prevalent in North America, the design, sizing, and implementation of the combined heat and power (CHP) outputs require further investigation. Based on commonly digested substrates, recommendations are provided for the type and size of machines available for generation of electricity. Implementation concerns are investigated for grid-tied...
In this paper, the operation conditions of Distributed Generation (DG) with Renewable Energy Sources (RES) are studied in detail. In the complex GRID simulation, Wind and Solar units are considered as RES and Modular Diesel and Gas-Turbine units as conventional sources. For Modular Diesel and Wind units the transient modes are simulated. Results of the analysis of these processes are given at different...
Two smart-grid topologies are analyzed in this paper. The first one has two main differences from the traditional grid, a dc-bus and a smart integration module (SIM), which interconnects the dc- with the ac-bus. The second topology has only one difference from the traditional grid, a special control unit (SCU), which is attached to each device before connecting to the grid. The first topology has...
