12 微电网系统提高能源可靠性的原因

介绍

Whether you are working in the mining industry or building a skyscraper, 不间断的能源供应至关重要. 不带电源, 你的工作很快就会停止. 微电网系统通过为系统提供必要的电力来提高可靠性.

今天, we will understand and discuss how the microgrid system can elevate energy reliability. 让我们知道!

What is a Microgrid?

A microgrid is a localized comprehensive energy setup that produces, stores, and provides energy to your installations. To maintain the energy flow, the microgrid power system works efficiently and has the following necessary components.

• Energy source, such as solar panels or utility
• Energy Storage setup, such as batteries
• Backup energy supply through the 发电机.

Compared to a traditional power grid, the microgrid systems operate in two different modes.

• Off-grid mode. In this mode, there is no connection with the utility grid. Microgrid Systems produce power locally and distribute it to the system.
• Grid-tied mode. It enables the utility grid connection and provides seamless energy when connected through the grid system.

Reasons why Microgrid Systems Elevate Energy Reliability

Microgrid Systems improve energy reliability through their quality production and distribution. We have added the key features that ensure energy reliability.

原因 #1: Local Power Generation

Remote power generation has several issues and drawbacks. 例如:

• Energy transmission takes a long time.
• Losses of energy are pretty common due to transmission.
• It causes financial losses due to remote transmission.

Microgrid Systems are pretty effective and offer localized energy production through multiple tools and methods. 例如, here are a few locally installed energy sources.

• 太阳能光伏 (光伏发电) 系统
• 风力涡轮机
• 柴油发电机组
• 天然气发电机
• 热电联产 (热电联产) 系统
• 燃料电池
• 小型水力发电系统 (适用时)

Once you generate the energy locally, it offers many benefits, 例如:

• Reliable energy production and transmission.
• No energy losses and better conservation.
• Improved energy independence.

原因 #2: Islanding Capabilities

Do you know what happens when your grid goes offline? 通常, when you are connected to the utility grid, a power outage causes the shutdown of the whole system for safety purposes.

But the good news is that with the microgrid systems. There is no need to worry about the shutdown cases in the microgrid. It can disconnect the grid automatically and provide power to the system non-stop.

This process is pretty effective and controlled through the smart control systems.

During Island Mode

During this mode, the microgrid keeps itself an independent source of energy. 它执行以下任务.

• 发电
• 电池储存
• 负载均衡
• 电压调节
• Frequency control

Do you know when island mode is suitable? It is the ideal solution during:

• Storm-related outages
• Wildfires
• Utility maintenance
• 电网不稳定
• Natural disasters

原因 #3: Multiple Energy Sources

Relying only on one source of energy is never a wise decision. More sources mean better reliability and easier availability of the energy.

The same goes here with the microgrid systems. Compared to traditional grid systems, they have multiple sources of energy during an outage and a normal power supply. 这些都是:

• Utility power
• 太阳能电池板
• 电池储存
• 柴油发电机组
• 天然气发电机

If a power shutdown occurs, battery storage and generators are there to save you from the hassles.

When one source of energy becomes unavailable, the microgrid systems cut it off and redirect energy production and supply through the second source.

原因 #4: Battery Energy Storage Systems (贝斯)

Undoubtedly, generators provide a non-stop energy supply in microgrid systems. But the best thing is the battery energy storage systems. They are an independent source of energy without the use of fuels.

The good thing is the instant power supply, which generators often don’t do. An energy management system helps during a power outage in the following ways.

• Batteries immediately supply electricity.
• Critical equipment continues operating.
• Backup generators start.
• The Energy Management System coordinates all power sources.

In addition to outages, batteries are also helpful during normal power supply cases. 例如, they help by:

• Storing excess solar energy
• 减少高峰需求
• Stabilizing voltage
• Supporting frequency regulation
• Improving power quality

原因 #5: Smart Energy Management System

Have you installed the smart energy management system in your microgrid systems? Microgrid Systems often have a smart energy management system. 它有助于监控:

• Electricity demand
• 可再生能源生产
• 发电机状态
• 电池电量
• Utility grid condition
• Equipment health

With this management system, energy efficiency remains high as the EMS system decides on:

• Power source to operate
• When should generators start
• When should batteries be charged or discharged
• Which loads receive priority
• How to optimize fuel consumption

With intelligent monitoring, it is easier to manage energy and enjoy a high-quality management system.

原因 #6: Faster Recovery After Grid Disruption

Grid Disruption occurs due to stormy weather or environmental disasters. If you have a traditional grid system, there is one key disadvantage during this grid disruption. It causes the shutdown of the whole system and disrupts the supply.

然而, microgrid systems offer better reliability in many ways. 例如, they offer a non-stop supply by reducing single points of failure.

When there is no grid supply available, they operate and produce energy independently. Once the grid energy is back, they:

• Synchronize with the grid
• Reconnect safely
• Return to normal operation
• Continue monitoring for future disturbances

原因 #7: Improved Power Quality

Microgrid Systems has many goals to complete. 例如, they handle the outage. But this is not their sole purpose of use. 反而, a stable and reliable energy supply is the necessary task to avoid damage to your home or commercial appliances.

Microgrid Systems do this very well by controlling:

• 电压波动
• Frequency variations
• Harmonics
• Voltage sags
• Voltage swells
• Short interruptions

There are no more risk factors for damage to:

• 医疗器械
• 数据服务器
• Industrial automation systems
• Laboratory equipment
• Telecommunications equipment

Your system has high power quality and gives an outstanding performance.

原因 #8: Reduced Single Points of Failure

The energy reliability of the traditional grid systems is very low. It is because you have a single point of failure; your whole system is going to shut down in no time.

例如, here are a few failure points.

• One transmission line
• One transformer
• One utility connection
• One power plant

If failure occurs at any single point, your whole system fails to receive power and experiences blackouts.

另一方面, microgrid systems are more reliable by offering a continuous energy supply with the right sources. 首先, microgrid systems cut off failure points to keep the energy supply constant.

They have:

• Multiple generators
• 电池储存
• Renewable energy
• Intelligent controls
• Multiple distribution paths

It means you get a constant energy supply when one generator or a distribution path gets affected.

原因 #9: Continuous Power for Critical Loads

Not every device or appliance should be operated. 反而, you have to decide whether and which equipment you should operate.

Based on the priority, we divide the appliances into three formats.

• 临界负载— they need essential operations. 所以, the basic goal is to run them continuously.
• Medium priority loads. They are also essential but can be shut down for a few minutes or hours depending on the energy supply.
• Non-essential Loads. It doesn’t matter if you operate these loads. They can go offline for several hours or during an outage.

Microgrid Systems focus on the operations of the critical loads, 例如:

• 手术室
• 应急照​​明
• 数据服务器
• 消防系统
• 通讯设备
• Industrial safety systems
• Water treatment controls

During outage hours, your necessary devices keep running while ignoring the unnecessary loads.

原因 #10: Better Load Management

The load requirements are never the same throughout the day. 例如, you have peak energy usage during the afternoon due to high heat and the operation of the air conditioners at home.

Power consumption is less in the morning, 晚上, and night. 所以, you should manage the load based on your needs. A microgrid power system balances the loads and powers the system with better load management.

例如:

• It schedules equipment operation to reduce the peak power consumption.
• Optimizes peak demand and stabilizes power consumption
• Prevents overloads by cutting off the unnecessary device operations.
• Balances generator output and streamlines the energy flow.
• It coordinates with the battery storage system to store extra energy and provide it during outage hours.

原因 #11: Improved Resilience During Natural Disasters

Natural disasters come uninvited and cause serious issues. Common examples of natural disasters are hurricanes, 洪水, 地震, wildfires, snowstorms, and severe thunderstorms.

Their impact on the utility grids and power transmission system is aggressive.

• Bring down the whole power distribution network.
• Shut down the utility grids and interrupt the energy supply.

Microgrid systems are very effective in handling power transmission and supply during disasters.

如何? They maintain the energy supply with the local energy production and distribution networks. The benefits of high energy reliability with the microgrid systems include:

• Continued operation during grid failures
• Reduced dependence on damaged transmission infrastructure
• Faster disaster recovery
• Enhanced community resilience
• Improved emergency response capabilities

Reason# 12: Reduced Transmission and Distribution Losses

With the traditional grid systems, the energy distribution occurs several kilometers away. The issue is not the transmission but the loss of power due to transmission and resistance in the power lines. It reduces the supplied energy and decreases overall efficiency.

Microgrid Systems also features a solution for such a situation. They produce the energy locally, reducing the remote transmission and supply. With the remarkable energy, strength, 和可靠性, you get the following benefits.

• Higher overall system efficiency
• Lower transmission losses
• Reduced stress on utility infrastructure
• Improved voltage stability
• Better energy utilization
