1、 The diverse demand background in the new power scenario

The current energy and power sector is forming new demands around four major directions:

1. Driven by the "dual carbon" goal: it not only requires energy conservation and carbon reduction on the consumer side, but also gives rise to new fields such as carbon emission rights and carbon asset trading. At the same time, rules such as carbon tariffs are also affecting market layout.

2. Deepening the reform of the electricity market: the rise of power sales companies, the expansion of peak valley differences in electricity prices, the adjustment of the "two-part system" electricity price application, and the gradual implementation of new models such as virtual power plants.

3. Industry and market development: The cost of photovoltaic and energy storage equipment has decreased, coupled with the rapid popularization of new energy vehicles and the large-scale construction of charging piles, promoting the upgrading of energy infrastructure.

4. User core demand: Enterprises are more concerned with reducing energy costs and increasing revenue, while also hoping to avoid the impact of "dual control of energy consumption" and improve electricity reliability. They also need to optimize the flexible expansion of transformers and energy management efficiency.

2、 From demand to scenario: three types of landing directions for "source network load storage"

Undertaking the diverse demand background mentioned above, the "Source Network Load Storage" project has formed three typical application scenarios:

Distributed light storage charging scenario:Matching users' needs for cost reduction and efficiency improvement, by constructing distributed photovoltaic, energy storage, and photovoltaic charging stations, combined with peak and valley electricity prices, policy subsidies, and other dividends, not only can energy utilization efficiency be improved, but also electricity costs can be directly reduced.

Scenario of coordinating multiple new energy sites:In response to the reform of the electricity market and the development trend of the industry, value-added services such as operation, maintenance, and energy-saving management will be carried out around multiple new energy sites, relying on the multi energy complementary model to explore new mechanisms for coordinated scheduling of source grid load storage.

Industrial parks and zero carbon factory scenarios:Adhering to the "dual carbon" goal and the requirements for park transformation, utilizing the spatial advantages of industrial parks, taking safety as the core premise, and combining with the construction standards of zero carbon parks, we will promote the park to achieve green and low-carbon upgrading.

3、 Six core pain points in the implementation of "source network load storage"

1. Pain points in power balance: The intermittency and randomness of new energy generation can easily lead to short-term power imbalances, and the seasonal mismatch between power generation and consumption exacerbates long-term power balance problems.

2. Pain points for system security and stability: The new power system has weak inertia and voltage support capabilities, complex dynamic characteristics, and faults that can easily cause safety accidents such as broadband oscillation and chain disconnection.

3. Pain points in electricity costs: To ensure system balance, the construction of auxiliary services and supporting facilities, resource regulation, and channel investment will all drive up energy usage costs.

4. Pain points of low-carbon energy consumption: Users need to simultaneously cope with multiple low-carbon constraints such as dual control of energy consumption, green electricity quotas, and carbon markets, and adjust their energy consumption methods to meet policy requirements.

5. Pain points in scheduling and control: With the integration of various links of source grid load storage and massive new energy and new loads, the observable, measurable, and controllable scheduling of the power system is facing severe challenges.

6. Pain points of intelligent operation and maintenance: The popularization of multi site and cross regional energy facilities places high demands on intelligent operation and maintenance of sites (such as heterogeneous data access, equipment diagnosis, etc.) to reduce costs and avoid hidden dangers.

4、 Solution for Six Pain Points: Microgrid Smart Energy Platform

Under the six major pain points of the implementation of "source grid load storage", the microgrid smart energy platform has become the core solution. It is a system that integrates IoT, big data, AI and other technologies (represented by AcrelEMS3.0), which connects various energy facilities to achieve monitoring, control and optimization of energy:

From an architectural perspective, the platform relies on the smart energy management cloud platform to achieve data integration, and connects with terminal devices in various scenarios, including 10kV/0.4kV photovoltaic grid connection, micro wind power, distributed energy storage, charging piles and other basic energy facilities. It also covers combination scenarios such as small-scale photovoltaic storage and charging, photovoltaic storage and diesel charging, and enterprise microgrids.

Its core value lies in solving pain points such as power balance, cost control, scheduling and operation through technological means, such as real-time matching of new energy output and load demand, optimizing scheduling strategies, achieving intelligent operation and maintenance of stations, ultimately improving energy efficiency, reducing waste, and adapting to the needs of "dual carbon" and power market reform.
