Problems and countermeasures of photovoltaic and energy storage construction

Should photovoltaic power generation be subject to price limits?

Recently, the National Energy Administration proposed a policy that the market-oriented trading of photovoltaic power generation shall not be subject to price limits and shall not be included in the peak and valley time of use electricity prices, which will inject new vitality into the development of the photovoltaic power generation industry.

Should energy storage power plants be exempt from peak shaving?

In addition, the new energy storage power plants and pumped storage power plants enjoy higher compensation standards and call priorities for peak shaving, and the exemption of wind power and PV power in auxiliary services for peak shaving also goes against the fairness and justice of the market.

Why is solar power a problem?

However, the root causes of the problem are a mismatch between the development of wind power and solar power and the current power system, immature technology, difficulty in absorbing wind and solar power across regions, and a lack of large-scale capability for absorbing wind and solar power on the demand side.

How much subsidy should PV energy storage facilities be paid?

It specifies that energy storage facilities constructed synchronously with newly installed PV power generation should be paid a subsidy within 600 euro. In addition, the subsidy paid to energy storage facilities added to existing PV power generation should be within 660 euro/kW. What's more, price policies for PSS are relatively perfect in the EU.

How can photovoltaic power generation enterprises benefit from market-oriented transactions?

Through market-oriented transactions, photovoltaic power generation enterprises will be able to participate in the market more flexibly, improve market competitiveness, and increase consumption.

What are the economic indicators of distributed photovoltaic power generation projects?

This paper conducts the economic analysis of distributed photovoltaic power generation projects, calculates profitability analysis indicators such as financial internal rate of return (IRR) of project investment, financial net present value of project investment, and payback period of project investment.
