A concentrating solar power plant can use a new type of solar power generation equipment to carry out the conversion of “solar-heat-electricity” and could maintain stable electric power output

which provides an effective way to enhance the capability of accommodating solar power output. A concentrating solar power plant is proposed to support the system operation in a combined heat and power(CHP)microgrid

in which a wind power station

an electrical energy storage device

and an electric heater are equipped. Then

retail electricity prices and retail heating prices in the microgrid are utilized as signals to induce users to participate in the demand response program. The demand price elasticity matrix is employed to model the response of the participated electrical loads and thermal loads in the demand response program. Considering the uncertainties of wind power and solar power outputs

a fuzzy chance constrained programming model is established with an objective of maximizing the operational benefit of the microgrid. Then

the model is simplified

and a mixed integer linear programming model is attained and solved by the well-developed commercial solver CPLEX. Finally

a sample microgrid system is used for demonstrating the presented model and method for a typical winter day and a typical summer day.
