Example of General hybrid power system model

A simple block diagram of a hybrid power system is shown in Figure. The sources of electric power in this hybrid system consist of a diesel generator, a battery bank, a PV array, and a wind generator. The diesel generator is the main source of power around the world. The output of the diesel generator is regulated ac voltage, which supplies the load directly through the main distribution transformer. The battery bank, the PV array, and the wind turbine are interlinked through a dc bus. The RTU (Remote Terminal Unit) regulates the flow of power to and from the different units, depending on the load. The integration of a RTU into a hybrid power system is important to enhance the performance of the system. The overall purpose of the RTU is to give knowledgeable personnel the ability to monitor and control the hybrid system from an external control center. Since the hybrid systems of interest in this research are located in remote areas, the ability for external monitoring and control is of utmost importance. The RTU is interfaced with a variety of sensors and control devices located at key locations within the hybrid system. The RTU processes the data from these sensors and transmits it to a control center. In addition, the RTU is also capable of receiving control signals and adjusting parameters within the system without the physical presence of the operating personnel.

A block diagram of grid interconnection unit

There is a significative difference storage system and electric power system interconnection unit. The microgrid usually has as high power from grid point of view that it is connected to medium voltage fine, typically 15 kV in Poland. Although the power system interconnection unit has almost the structure as storage system, its primary voltage is in range of kilovolts and is sinusoidal. So, it requires different power electronic converter. It is assumed in Poland that all devices connected to 15 kV lines have to be joined using 50 Hz transformer. Hence, the grid interconnection unit can have a structure shown in Figure.

A block diagram of electrochemical energy storage

The energy storage systems operating in the microgrid are usually electrochemical ones, based on lead-acid battery. Typical estructure is shown in Figure. The microgrid and battery voltages are typically in range of 1000 V and rather similar.

Microgrid operation of islanded operation

The figure illustrates the concept of the power management method in the islanded mode. When a DC micro-grid must be separated from the ac grid and switch to the islanded mode, the grid-tied converter released control of the DC grid voltage and one of the converters in the micro-grid must take over that control. Since each converter of DGs is used for optimal control of each source, only the converters of the energy storage elements are free to regulate the DC grid voltage. During the islanded mode, the battery plays a main role in regulating the DC grid voltage and the super-capacitor plays a secondary role in responding to the sudden power requirement as an auxiliary converter.

Simplified layout of a dc microgrid

The dc microgrid considered is schematically shown in Fig. As for a typical dc microgrid, it consists of the following mainelements:
• variable (nondeterministic) generations and, in this example, a wind turbine using permanent-magnet synchronous generator (PMSG); the maximum power output from the wind turbine is largely determined by the wind condition;
• controlled (deterministic) generation (e.g., a diesel generator or with ac grid connection); as shown in Fig, the dc grid in this example is connected to an external ac system via a dc-ac converter which provides bidirectionalpower-flow capability;
• variable loads with different characteristics; a number of ac and dc loads can be anticipated (e.g., ac loads via dc-ac inverters, dc loads via dc-dc converters, and direct-connected dc loads, etc.);
• energy storage (ES) system to accommodate the presence of variable generation and load, and the requirement of possible island operation (i.e., connection to the external ac system being lost)

The DC microgrid based on modular PV generation system

The DC bus coupled microgrid investigated in this paper is shown in Fig. 1. DC/DC converters for PV modules, a bidirectional DC/DC converter for battery, a bi-directional DC/AC converter and local loads share a DC bus. The modular photovoltaic generation system is the key element in this DC microgrid, which consists of three DC/DC converters with modular design and same ratings. These  modular converters transfer the power generated by PV arrays to DC bus. The battery with bi-directional DC/DC
converter is used to balance the power differences between PV power supplies and local loads in islanding mode. The local loads include the auxiliary power supplies for microgrid operations, such as control/monitoring of PV arrays, battery monitoring, control/driving of converters. The bi-directional DC/AC converter is used to realize the connection between DC microgrid and AC grid

During operation a microgrid, sometimes; renewable energy sources and the external power grid, dispatched electric energy simultaneously. Sometimes, many sources is neccesary for supply to electric load. Also, all it, considering both economic and technical criteria. The figure represent la connection and disconnetion of sources for each state of performance of a microgrid. Too, it is applicable to other similar electric systems.


energy of each source accumulate

In a microgrid, each energy source is required according to the criterion of costs and production capacity. During the operation time, accumulative energy from each source is represented in the figure. Criteria of linear optimization has been used in this modelling and simulation. This allows determining the nominal capacity and the ability to respond to sudden requests. Made on Matlab of MathWorks Inc.

single-line diagram of the test power system including the advanced DES systems

En este post muestro el ejemplo que han usado para analizar la performance de un sistema eléctrico que cuenta con un Distribuited Energy Storage (almacenamiento de energía distribuida… o su equivalente en español). Muchos de estos escenarios no han sido construidos porque toda vez, éstos se están recién investigando en el mundo, y lo que se ha podido construir son casos puntuales en que casi a medida del laboratorio, universidad o institución de investigación se han implementado. Observen la cantidad de potencia que está involucrada y a eso apunta el mercado eléctrico, a una implementación masiva de estas soluciones en los mercados nacionales. Cargas eléctricas, barras y elementos de acondicionamiento de energía eléctrica desarrollados con electrónica de potencia son esenciales en estas implementaciones, que me encargo de estudiar y por medio de este blog compartir con la comunidad de habla española y a quienes usan el traductor del blog (en inglés).
