Project Summary

Pakistan is a poor country, with a per capita gross domestic product (GDP) of US$1,909 in early 2019, and 58 million people lack access to electricity. Although it is a small emitter of carbon dioxide (CO2), unlike India or China, Pakistan is likely to increase its greenhouse gas emissions, depending on the fuel choices and investments it makes. 

A Virtual Power Plant is a network of decentralized, medium-scale power generating units such as wind farms, solar parks, and Combined Heat and Power units, as well as flexible power consumers and storage systems. The interconnected units are dispatched through the central control room of the Virtual Power Plant but nonetheless remain independent in their operation and ownership.

 The high proportion of rooftop solar generation in the country's electricity network makes it an ideal location to test the potential for a virtual power plant (VPP) to help stabilize the grid while delivering extra value to customers, the networks, and the retailer.

Project Objectives

The objective of a Virtual Power Plant is to relieve the load on the grid by smartly distributing the power generated by the individual units during periods of peak load. Additionally, the combined power generation and power consumption of the networked units in the Virtual Power Plant is traded on the energy exchange.

the eco-friendly energy will be produced, which will help reduce the emission of greenhouse gases like co2, methane, etc. the consumer becomes independent of WAPDA  ownership of power generation.

Using market prices, the control system can create optimized price schedules which ramp up or down flexible power consumers (like an industrial pump) which allow for the consumption of electricity when it is cheap and demand is low. 

Project Implementation Method

Virtual Power Plants rely upon software systems to remotely and automatically dispatch and optimize generation-or demand-side or storage resources in a single, secure web-connected system

It is divided into two sections technical and commercial.         Technical implementation is the production of energy by renewable energy resources(solar and wind), and software-based management of produced energy. The technical operation includes real-time and scheduled operations, aggregation, forecasting functions, and DER maintenance and submission.

A Virtual Power Plant can be combined into different business models, according to local market and regulatory conditions. The basic application is the aggregation of distributed generation plants via centralized control system. This enables utilities and other operators of decentralized energy resources to monitor the feed-in values of the plants in real time and - by processing further data, for example weather forecasts – they can forecast the generation of decentralized energy resources more precisely. These forecasts help the aggregators to accurately realise their trading strategies on power exchanges.The ability to monitor and forecast the behaviour of decentralized energy resources gives valuable insights on possible bottlenecks in the grid.
In addition to monitoring, the operator of the Virtual Power Plant can also control and steer networked plants, which opens the door to a whole range of interesting applications. These can be dispatching groups of plants to provide control energy, changing generation of steerable technical units to ensure they generate only in lucrative times of the day or curtailing wind power in the event of an excess supply of electricity and negative market prices.

Benefits of the Project

The VPP can potentially provide a  cost-effective solution in the medium term to smoothing out intermittent renewable energy generation and avoiding expensive upgrades to network infrastructure to meet peak demand.

The Virtual Power Plant will produce carbon-free energy that is very good for the environment. We will limit the use of fossil fuel-based energy production.

Every unit in the community will be able to sell extra produced energy, so it will be a way of earning for consumers.

This system has benefits such as the ability to deliver peak load electricity or load-following power generation on short notice. Such a VPP can replace a conventional power plant while providing higher efficiency and more flexibility.

.This will be our biggest backup for energy. Supporting the grid via your battery to help prevent blackouts during times of high demand such as the hottest days of summer, or generator failures. Helping to build a modern electricity grid that supports more renewable electricity to be added to the grid

Technical Details of Final Deliverable

The participants of the Virtual Power Plant (VPP) are connected to the VPP’s central control system via a remote control unit. This way, all assets can be efficiently monitored, coordinated, and controlled by the central control system. Control commands and data are transmitted via secured data connections which are shielded from other data traffic due to encryption protocols.
In addition to operating every individual asset in the Virtual Power Plant along with an optimized schedule, the central control system uses a special algorithm to adjust to balancing reserve commands from transmission system operators, just as larger conventional power plants do.

The central control system of the Virtual Power Plant processes a wide range of information. This includes data of all networked plants, current prices at the power exchange, weather and price forecasts as well as grid information of the system operators. By using weather data and static system data as location or inclination angle of PV modules, the feed-in of the networked assets can be forecasted. On the day of the actual feed-in, live data continuously improve the forecast and enable the adjustment of deviations.
