M&S Logistics Park 300KW Micro-grid energy storage project

Project Name: M&S Logistics Park 300KW Micro-grid energy storage project in PeterBorough city, UK

Subject: As one of UK’s leading retailers, M&S has more than 1,382 stores around the world. It is committed to delivering sustainable value for its stakeholders and making every moment special through the high quality. Its own brand food, clothing and home products could be offered in its stores and online both in the UK and international.

System solution: The micro-grid energy storage project’s PV (photovoltaic) is 1MW and was finished installation by another company (its PV inverter is from DELTA). The 150KW PCS (power control system) was provided by Shenzhen Sheng Hong Company. Sacred Sun was only responsible for the energy storage part of the Micro-grid energy storage project. The energy storage system contains 2 containers and each container was composed of 288 pcs FCP-1000 lead carbon batteries, two group batteries in two containers were connected in parallel. Each container was equipped with air conditioning and ventilation equipment.

Application scenarios: Since all large PV power plants, wind power plants, nuclear power plants were running direct on-grid during the day (10 am to 5 pm); such logistics park small PV site is not able to connect to the grid limited by technology in UK. In view of this, the small energy storage PV system has to storage the electricity generated by itself for personal using or sell to the state grid at night (5 pm to 11 pm).

Figure 1. Composition of Off-grid PV System

2. Major Components of Off-grid PV System

   1). Solar-cell Array. It is the core component of the system, convert solar energy into electric energy. The solar cell modules are installed in series or in parallel in accordance with the requirements of different systems.

   2). Battery. Store the electric energy generated by solar-cell array so as to supply power at the following conditions: light deficient conditions, nights, or when load demand is higher than power supply of the array. The most widely applied batteries in PV systems are lead acid batteries.

   3). PV Controller. It is the core control section of the whole system, controlling the charge/discharge of batteries and the electrical power output of the array and battery pack. Currently, there are mainly two widely applied control modes: PWM and MPPT. The PWM has higher control efficiency but relatively lower utilization rate to solar modules; while MPPT has relatively lower control efficiency but higher utilization rate to solar modules. In most cases, PWM mode is applied in system with smaller power, and MPPT mode is applied in system with lager power, especially when system power is higher than KW level.

   4). Inverter. If AC Load is included in the system, inverter is needed to concert direct current from solar-cell array or battery pack into needed alternate current.

Hydrogen Fuel Battery

  In previous article, we have discussed the technical requirements for electric vehicle batteries and have briefly introduced the basic characteristics of Li-ion batteries and lead acid batteries. Start from this article, we will introduce several advanced batteries for you one by one. In this article, we focus on hydrogen fuel battery.

    Fuel battery is usually nonrechargeable. As a kind of fuel battery, the “charging mode” of hydrogen fuel battery is actually hydrogen filling.

   The advantage of hydrogen fuel battery is 0 pollutant emission. Hydrogen generates electricity, motor drives vehicle. We change gas stations into hydrogen refueling stations and everything seems to be Ok.

   However, the entire process is not as simple as what you see. One problem we need to consider is the manufacture, transportation, and storage of hydrogen. Gaseous hydrogen needs to be stored in high pressure gasholder while liquid hydrogen needs to be maintained at very low temperature which costs excessive consumption of electric energy. It is far more troubling than fuel oil.

    Manufacturing of hydrogen is relatively simple. But if you want to transport hydrogen to hydrogen refueling station, special pipelines are needed. Considering the hydrogen embrittlement, the transportation, storage, and refilling of hydrogen demand facilities with high security.

     For fuel oil and natural gas, we have existing infrastructures to utilize; for lithium battery, we have existing power grid to utilize; while for hydrogen fuel battery, we have nothing. If we plan to manufacture vehicles with hydrogen fuel batteries, we need to build an entire system from hydrogen manufacture, to transportation and storage first. It is really a costly project.

Which Battery is Best for New Energy Vehicle?

Recently, with the promotion of Tesla, more and more new-type batteries for new energy vehicles begin to enter the public consciousness: from hydrogen fuel battery, aluminum battery, to flow battery, grapheme battery, aluminum ion battery, ... It seems that Li-ion battery has been out of date. What on earth is the truth of electric vehicle batteries?

    Now, let’s uncover the truth of electric vehicle batteries.

    Battery is the core problem which limits the development of electric vehicle. For electric vehicles, ideal battery must possess following characteristics:

   1. Enough energy density (has enough capacity at per unit volume and per unit weight), so that the vehicle could run further;

    2. Enough power density (could generate enough power at per unit volume and per unit weight), so that the vehicle could speed up in a short time and achieve climbing;

    3. Fast energy supplements, no matter recharging or replacing;

    4. Low average cost, with competitive advantage on comprehensive analysis of service life and price.

    In current electric vehicle market, there are mainly two kinds of batteries: Li-ion batteries (LFP battery, LMO battery, ternary lithium battery) for high-speed electric vehicles, and lead acid batteries for low speed electric vehicles.

   For Li-ion batteries, the power density and energy density are satisfying, but its recharging time is long and price is relatively high. While for lead acid batteries, although its power density and energy density is relatively low and its recharging rate is slow, its low price result in its extensive application on low-speed and short distance electric vehicles.

   In following passages, we will introduce the advanced batteries mentioned above for you.

Progress of Sacred Sun’s Lithium-ion Battery

• In view of the fierce competition of Lithium-ion battery in the communication market, reducing cost and lowering price is the only approach to consolidate and increase our market share. To achieve the objective of cost reduction and meanwhile improve the property of our Lithium-ion battery, we have made great achievements in the following aspects:

  1. Dry blending technology is applied in powder mixing process to shorten ingredients preparation time and improve the uniformity and adhesion of plates;

  2. Dispersion technology of pigment industry is brought in to achieve the molecular-level dispersion of paste;

  3. Roughen the surface of the aluminum foil (positive electrode) and copper foil (negative electrode) to improve the adhesion of paste and foils, and thereby prolong the service life of batteries;

  4. Adopt LiFePO4 made from iron oxide red craft instead of LiFePO4 made from iron oxalate to reduce cost;

  5. Adopt ovens with high vacuum degree to shorten the drying time of plates and meanwhile make sure the property of products.

  

Capacity of Global Distributed Energy Storage Systems May Increase by 10 Times in Future 3 Years

    In accordance with data from Navigant Research---a well-known American market research firm, the capacity of global distributed energy storage systems will achieve 276 MW by 2015.

    With the increasing support from governments and increasing energy storage demands from grid operators and electric power companies, the capacity of global distributed energy storage systems may increase by 10 times and up to approximately 2400 MW by 2018.

    The report also pointed out that influenced by the rapid development of battery technologies, the distributed energy storage market will also see rapid growth in recent years. Meanwhile, the popularization of PV, EV, EV charging stations, and household energy networks will generate new demands for distributed energy storage systems.

    It is expected that by 2024, the capacity of global distributed energy storage market may increase to 12,000 MW. However, to achieve this objective, researchers must overcome difficulties on cost control, software development, control system design, and integration technology optimization.
