A mixed power grid model of wind power and thermal power was built. The largest output power of wind power and thermal power was gotten by simulation in the condition of ensuring the safety and stability of the grid. Taking largest output power as the boundary condition in economical analysis of the grid, the load dispatch scheme for wind power and thermal power was developed to ensure the optimal economy of the grid.

Aimed to solve the abandoned wind problem and reduce CO2 emission in the power generation process, this paper put forward a thermal, wind power and pumped storage power station co-operation cost-benefit analysis model. And through a simulation example, found that using pumped storage power station to substitute thermal power as the alternate service for wind power, and absorb underused wind power, can reduce the use of fired units and increase the capacity of grid to absorb wind power, as well as reduce CO2 emission. Then through the sensitivity analysis, found that the amount of grid-connected wind power is a sensitive factor of CO2 emission reduction and the decrease of grid power purchase profit. So when grid implementing wind power grid connection, should use pumped storage power station as the wind power alternate service to promote wind power grid connection.

The average wind power in China increases year by year, obviously wind power output volatility and uncertainty that makes the large-scale wind power grid to bring a lot of problem, such as peaking and frequency modulation, voltage regulator, stability, power quality problems, etc. The power structure in China is given priority with coal-fired thermal power, peaking power is relatively scarce. Lack of wind power on a large scale grid has intensified. The paper briefly analyzes the power grid network frame structure, load and power characteristics in Gansu province. Considering the measured data in 2014 of Gansu power network, intuitive shows Gansu power grid fluctuation characteristics of wind power output in different period of time, discussed the influence of wind power grid peak shaving capability. It improving the large-scale wind power access after the measures of Gansu power grid peak shaving capability.

Most power systems in underdeveloped and developing countries are based on conventional power plants, mainly "slow-response" thermal power plants and a certain number of hydro power plants; characterized by inflexible generating portfolios and traditionally designed to meet own electricity needs. Taking into account operational capabilities of conventional power systems, their development planning will face problems with integration of notable amounts of installed capacities in wind power plants (WPP). This is what highlights the purpose of this work and in that sense, here, possible variations of simulated output power from WPP in the 10 minute and hourly time interval, which need to be balanced, are investigated, presented and discussed. Comparative calculations for the amount of installed power in WPP that can be integrated into a certain power system, according to available secondary balancing power amounts, in case of concentrated and dispersed future WPP are given. The stated has been done using a part of the power system of Bosnia and Herzegovina. In the considered example, by planned geographically distributed WPP construction, even up to cca. 74% more in installed power of WPP can be integrated into the power system than in case of geographically concentrated WPP construction, for the same available amount of (secondary) balancing power. These calculations have shown a significant benefit of planned, geographically distributed WPP construction, as an important recommendation for the development planning of conventional power systems, with limited balancing options.

Optimizing Model

Wind energy curtailment to reduce wind power and solving wind power grid connected problem is the key element to increase wind power grid-connected and promote renewable energy development. Firstly, from the perspective of clean energy development ,utilization and increasing in wind farm investment income, this paper has analyzed the reason of wind energy curtailment, and summarized effective policies for the management of wind energy curtailment from all over the world. On this basis, this paper considered the loss of interest of thermal units during wind power peak regulation, in order to enhance the enthusiasm of thermal units to participate wind power and thermal power bale delivery, this paper has established wind power, thermal power bale delivery model of calculation of interest. From the numerical example, we conclude that after wind power and thermal power generation rights trading, the wind turbine will get higher revenue due to higher pool purchase price,while thermal power units are exposed to a loss because the tradeoff price is lower than the stake electrovalence.

Based on security constraint economic dispatch module, and with wind power prior utilization as target, the day-ahead optimum dispatching model of wind-thermal power is constructed to improve the acceptance ability of intermittent new energy generation. The practical application in Jibei power grid indicates that this model can meet the compiling requirements of day-ahead generation schedule, realizes the prior acceptance of wind power and contributes to the energy saving and emissions reduction in power field under the power grid security constraint.

Subject. This article discusses the effectiveness of government programmes to support renewable energy and whether they should continue to be implemented. Objectives. The article aims to conduct a comprehensive analysis of the changes in solar and wind power projects under the State support programme within the period from 2014 to 2019 and assess the effectiveness of the acting incentive mechanisms. Methods. For the study, I used the Learning-by-Doing theory and Project Management principles and methods. Results. The article proposes to consider the local content of the projects implemented as the key effectiveness indicator of the renewable energy support programme in Russia. For solar projects, this figure is currently significantly higher than the planned one, and it corresponds to the planned one for wind projects. In general, therefore, the programme can be considered effective. Conclusions. Further improvements in renewable energy support mechanisms should take into account the need to drastically increase the pace of training in the full cycle of the renewable energy project, including the operation phase of generating equipment and the supply of electricity to the grid.
