Industrial & Commercial Storage Project

ContextNetwork Issues


Climate change is

happening

Reduction in centralised generation

Constrained and

overloaded grid

Rapidly increasing sale of EVs

EVs are part of electrical

energy systems

Increase in distributed generation

New loads and load

profiles on the grid

A strong future for

distributed storage

Smart systems require control

A typical demand increase in EVs

From the start of data collection (Q2, 2012) the cumulative Electric Vehicle (EV) data shows a sustained and dramatic growth of the EV car and van market

In Q2, 2012, there were 3,000 registered EV’s on the road

By Q2, 2014, this had rose to over 10,000

After this time there was exponential growth

The latest results Q3, 2016, shows 90,000 registered EV’s


The future strategy for managing the grid Statement: There is an increase in demand for electric vehicles The grid can do one of three things to cope with this demand:

Option 1: Introduce more capacity to the grid through generation and expand the networks capacity

Option 2: Introduce more flexible generation in order to deal with spikes seen from chargers

Option 3: Introduce local storage to greatly reduce the demand spike by using storage to deal with the ramp up of power

Option 3 is the most cost effective for the network as options 1 & 2 both require the local, and eventually, the national network to be upgraded in order to handle the capacity increase / capacity potential.

Project Aims & Objectives

Promote innovation, flexibility and non-network solutions (50kW, 210kWh) Engage with Industrial and Commercial Customers to test Energy Storage Systems Determining the scope of terms and conditions and practical implications of using

batteries on the LV networks Attitudinal analysis and performance assessment of participants within the commercial

environment Development of new policies, processes and systems to support commercial

deployment of Energy Storage Systems Provide knowledge to inform new regulations.


Trial sites


Cardiff

Taunton

Spilsby

Boston

Operating modes

Varied test configurations at 4 WPD sites


Spilsby

At peak demand, storage can be used to eliminate

peaks

Taunton

Demonstrating Backup/Islanding

Sensing either grid failure or a simulation of grid failure the energy storage system then

energises the selected maintained loads

Boston Cardiff

Active control by WPD – Own controller and scheduling

tools

Flexibility and scalability for various trials -Operating the

site at constant load, constant voltage, etc.

FFR, Triad Avoidance and DUoS Charge reduction

UK “Standard Battery Storage” approach. Most common use

case today in the UK

Peak Shaving + PV integration

Site works Delivery of the Energy Storage units to site (s)

– June 2017

Civil works – Plinth – all sites

Electrical connections: Spilsby – 27th of July - No shutdown Boston 25th of July - Shutdown for 3hrs Cardiff – 29/30th July. New busbar

installed for connection due to insufficient capacity in existing DB

Taunton – Planned for November

Commissioning: Spilsby – 14th August Boston – 16th August Cardiff – 9th October Taunton - December

What does this mean to a customer?

Deliver more options for customer connections through alternative connections –develop an alternative connection agreement for behind-the-meter

Triad avoidance Lower future DUoS charges due to the reduced reinforcement requirements Overall reduction in power consumption due to onsite generation Access to the flexible market Through storage customers can support the local grid independently and reduce strain

on the network


LV Connect & Manage Project

Low carbon technology (LCT) connections on LV network:

LV Connect and Manage

Trend for ‘clustering’ Hard to predict and plan ahead reinforcement Traditional reinforcement is expensive and takes time Delayed customers’ connections Reverse Power Flow (RPF) impact on distribution network

Presenter

Presentation Notes

-Social – demographic environment - maintain the highest standard to service to its customers, WPD plans to connect them as quickly and cost-effectively as possible and then actively manage them, once connected.


LV Connect & Manage outline

£1.7m NIA project (April 2016 - March 2019) Ability to provide more power during non – peak hours Bi-directional power flow control via “Domestic Load Controller” (DLC) hardware Accelerate connection of LCTs (storage, EVs, heat pumps) Protect WPD assets from overload 6 distribution substations and 100 customers in Furzton, Milton Keynes (Energy

Storage) and West Bridgford, Nottingham (EV chargers)

Presenter

Presentation Notes

Development of a smart interface point for domestic customers. This will give customer the ability to take larger amounts of power from the network when circumstances allow. It will also allow us protect assets from overload under exceptional circumstances when we would have the ability to turn down customer equipment such as chargers for electric cars.


Objectives

The project objectives are to trial and demonstrate:

Smart ANM solution for LV network Possibility of load management, as an alternative to network reinforcement BPL communication - Broadband over powerline (substation to customers’ homes) New business processes, based on proven, off-the-shelf technology, which can be

quickly and cost effectively deployed

Presenter

Presentation Notes

The objectives of this project are to trial and demonstrate the following: 1.Broadband over powerline, providing the communications solution between distribution substations and customers (enabling the bi-directional power flow control of LCTs) 2.ANM solutions with intelligence distributed into the LV network to monitor and control LCTs in real-time and optimize import / export patterns within operational limits 3.ANM solutions, as a short or long term alternative to network reinforcement, in areas where network constraints are becoming a problem due to the localized uptake of LCTs 4.New business processes, based on proven, off-the-shelf technology, which can be quickly and cost-effectively deployed to connect and manage LV customers’ LCTs.

LV Connect and ManageCustomer benefits

Intelligent interface to accelerate connection of LCTs (storage, EVs, heat pumps)

Avoid costly reinforcement Reduced amount of street works Provide flexibility to export more power

during non – peak hours or/and use stored energy in ‘self consumption’ mode

Consume energy in more sustainable, environmentally friendly way. Reduce amount of CO2 emissions
